About the Authors Brian Morgan, CCIE No. 4865, is a consulting systems engineer with Cisco special-

izing in collaboration technologies. In over 20 years in the networking industry, he has performed in a number of roles, including pre- and post-sales engineering, network consultant, Certified Cisco Systems Instructor, and engineering director for a telecommunications company. When he is not spending time with family and friends, Brian enjoys working with local high school and college students participating in local Cisco Network Academy programs, as well as STEM and FIRST Robotics programs in North Texas. Jason Ball is married to his beautiful bride of 18 years, Siobhan Ball. They have two

children, Isaac and Maureen. Both children have caught his passion for the technology industry. They are both involved in a robotics program through FIRST Lego League, with his wife coaching both their teams. Through this program, they learn skills like programming, electrical engineering, mechanical engineering, civil engineering, and other skills like gracious professionalism. Outside of this program, his daughter is getting into software design, and his son is taking courses through North Carolina State University called Young Engineers, offered for children between 12 and 18 years of age, where he is furthering his IT skills. Jason was a slow starter in the IT industry. His beginnings date back to 1989 with an opportunity to work with audio/video systems. In 1993, his focus changed to public speaking. He traveled around for many different types of speaking engagements, encountering groups of varying ages. In 2003, he was introduced to multicast media. This unfamiliar and exciting opportunity rekindled a desire for involvement in technology. In 2009, a new opportunity presented itself. Jason was recently unemployed when a connection with Scott Waschler, an employee at TANDBERG, opened a door to contract as a technical trainer. In May 2010, Cisco purchased TANDBERG, and a new world of technology emerged. This is a journey that will never end, and Jason is continually hungry to learn all he can and to share that knowledge with others who are also eager to learn. Jason currently works for Compass Business Solutions, a Learning Partner of Cisco. Compass specializes in teaching Collaboration-related courses, including CIVND 2. He holds many certifications, most of which are with Cisco. His current certifications with Cisco include CCNA Route/Switch, CCDA, CCSI, CCNA Video, CCNA Voice, CCNA Collaboration, CCNP Voice, CCNP Collaboration, CSE, LVCI, BACI, Cisco Video Network Specialist, and TVS Certified Specialist.

About the Technical Reviewers

About the Technical Reviewers Jhun DeLeon is an industry veteran when it comes to voice, video, and data networking,

having deployed numerous complex TelePresence/videoconferencing projects for large companies with global presence. When Cisco started selling TelePresence solutions, Jhun shifted his focus to TelePresence, or what is called collaboration. Jhun worked at Cisco System as a voice engineer working on unified communications. After Cisco, Jhun has worked with Cisco Partners doing design, architecture, and implementation of unified communications, TelePresence, videoconferencing, digital signage, and physical video surveillance. Marcello Federico is a technical leader in the Cisco Collaboration Technology group,

focused on video technologies and collaboration APIs. He is currently a consulting systems engineer covering the Pacific Northwest Enterprise segment where he works with his customers on creating their unified communications architecture and strategy. Prior to Cisco, Marcello held various systems engineering roles focused on the Enterprise, selling DSP media processing blades, software SDKs, and API stacks. Marcello graduated from the University of Western Ontario and obtained a degree in computer science with a specialization in software engineering. He loves to write code and continues to learn about the latest programming techniques and how to apply them to the Cisco collaboration APIs. He lives in Seattle, WA with his wife, Denise; children, Domenic and Cole; and his trusty old cattle dog, Chester. In his spare time he enjoys playing soccer and golf and spending time with his family.

Dedications Brian Morgan: This book is dedicated to Sunshine and the pursuit of much and more.

Jason Ball: To my wife, Siobhan. I couldn’t do what I do if you didn’t do what you do.

Acknowledgments

Acknowledgments Brian Morgan: This book would not have been possible without the support and assis-

tance of my awesome team in SLED West Collaboration, in particular Mike Popovich and Luc Bouchard. Their willingness to accommodate the erratic schedule (and moodiness) that has accompanied the writing of this book has left me astounded. A huge thank-you is not nearly sufficient for the efforts, patience, guidance, and professionalism of the editorial team: Brett Bartow and Christopher Cleveland. Most of all, I want to thank my co-author, Jason Ball. He is, without a doubt, the master of the diving catch. Jason Ball: Special thanks must be given to James Lehto, who helped open the door for

me to write this book. My co-author, Brian Morgan, has proven to be a great asset and a new friend. Thanks must also go out to Brett Bartow and Christopher Cleveland for their patience and proficiency throughout this process. My co-worker, Jeff Hubbard, has been an invaluable asset, sounding board, and punching bag for me to abuse while writing this book. If he had to hear me say “I’m writing this book” one more time, I might have become the punching bag. You have proven to be a great friend, and for that I am truly grateful. Finally, I must acknowledge my wife. You have been more supportive than I could have ever asked. You have carried the slack, encouraged me, and pressed me at exactly the times that I needed it. The success of this book is as much to your credit as it is to mine.

Command Syntax Conventions The conventions used to present command syntax in this book are the same conventions used in the IOS Command Reference. The Command Reference describes these conventions as follows: ■

Boldface indicates commands and keywords that are entered literally as shown. In

actual configuration examples and output (not general command syntax), boldface indicates commands that are manually input by the user (such as a show command). ■ ■

Italic indicates arguments for which you supply actual values. Vertical bars (|) separate alternative, mutually exclusive elements.

■

Square brackets ([ ]) indicate an optional element.

■

Braces ({ }) indicate a required choice.

■

Braces within brackets ([{ }]) indicate a required choice within an optional element.

Introduction Professional certifications have been an important part of the computing industry for many years and will continue to become more important. Many reasons exist for these certifications, but the most popularly cited reason is that of credibility. All other considerations held equal, the certified employee/consultant/job candidate is considered more valuable than one who is not.

Goals and Methods The most important, and somewhat obvious, goal of this book is to help you pass the CCNA Collaboration CIVND exam (210-065). In fact, if the primary objective of this book were different, the book’s title would be misleading; however, the methods used in this book to help you pass the CCNA Collaboration CIVND exam are designed to also make you much more knowledgeable about how to do your job. Although this book and the accompanying CD together have more than enough questions to help you prepare for the actual exam, the method in which they are used is not to simply make you memorize as many questions and answers as you possibly can. One key methodology used in this book is to help you discover the exam topics that you need to review in more depth, to help you fully understand and remember those details, and to help you prove to yourself that you have retained your knowledge of those topics. So, this book does not try to help you pass by memorization, but helps you truly learn and understand the topics. The CCNA Collaboration CIVND exam is just one of the foundation topics in the CCNA Collaboration certification, and the knowledge contained within is vitally important to consider yourself a truly skilled routing/switching engineer or specialist. This book would do you a disservice if it did not attempt to help you learn the material. To that end, the book will help you pass the CIVND exam by using the following methods:

Introduction ■

Helping you discover which test topics you have not mastered

■

Providing explanations and information to fill in your knowledge gaps

■

Supplying exercises and scenarios that enhance your ability to recall and deduce the answers to test questions

■

Providing practice exercises on the topics and the testing process via test questions on the CD

Who Should Read This Book? This book is not designed to be a general networking topics book, although it can be used for that purpose. This book is intended to tremendously increase your chances of passing the CCNA Collaboration CIVND exam. Although other objectives can be achieved from using this book, the book is written with one goal in mind: to help you pass the exam. So why should you want to pass the CCNA Collaboration CIVND exam? Because it is one of the milestones toward getting the CCNA Collaboration certification (no small feat in itself). What would getting the CCNA Collaboration mean to you? A raise, a promotion, recognition? Would it enhance your resume? Perhaps it would demonstrate that you are serious about continuing the learning process and that you are not content to rest on your laurels. Maybe it would please your reseller-employer, who needs more certified employees for a higher discount from Cisco. Or one of many other reasons.

Strategies for Exam Preparation The strategy you use for the CCNA Collaboration CIVND exam might be slightly different from strategies used by other readers, mainly based on the skills, knowledge, and experience you already have obtained. For instance, if you have attended the CICD and CIVND courses, you might take a different approach than someone who learned collaboration architecture via on-the-job training. Regardless of the strategy you use or the background you have, the book is designed to help you get to the point where you can pass the exam with the least amount of time required. For instance, there is no need for you to practice or read about IP addressing and subnetting if you fully understand it already. However, many people like to make sure that they truly know a topic and therefore read over material that they already know. Several book features will help you gain the confidence that you need to be convinced that you know some material already, and to also help you know what topics you need to study more.

210-065 CIVND Exam Topics Table I-1 lists the exam topics for the 210-065 CIVND exam. This table also lists the book parts in which each exam topic is covered.

CCNA Collaboration CIVND 210-065 Official Certification Guide The objective of this book is to help you pass the CCNA Collaboration CIVND exam (210-065). While you are learning about topics that can help you pass the CIVND exam, you will also become more knowledgeable about how to do your job. Although this book and the accompanying CD have many exam preparation tasks and example test questions, the method in which they are used is not to simply make you memorize as many questions and answers as you possibly can. The methodology of this book helps you discover the exam topics about which you need more review, fully understand and remember exam topic details, and prove to yourself that you have retained your knowledge of those topics. So this book helps you pass not by memorization, but by helping you truly learn and understand the topics. The

CHAPTER 1

Introduction to Video Communications High-quality, immersive video capabilities provide what may be the single most transformative technology available today. Through the use of prescriptive best practices, Cisco has pushed video into the technological spotlight. These prescriptive recommendations are made available on Cisco.com as Cisco Preferred Architecture guides. These preferred architecture guides are written specifically for design and deployment engineers and are referenced throughout this book. Video has long been seen as a gimmick technology, at best. A number of conditions have contributed to the view that video is simply not viable as a communication medium. Thankfully, the current generation of video technologies and offerings has greatly changed that view. This chapter provides an overview of potential video use cases and architecture.

With video integrated into the desk phone, either directly or through the use of Cisco Jabber (with desk phone control and a webcam), the user experience is greatly enhanced. Face-to-face communication tends to be more productive and consistently engaging than audio only. One side effect of video, for better or worse, is a reduction in multitasking. Conversations and interactions are more productive simply by virtue of making eye contact with a colleague in the next office or half a world away. All communications within the office can now be face to face. Of course, the option always exists to mute the video on a bad hair day.

Video Meetings and Conferences There was a time when the very mention of a videoconference spread fear, uncertainty, and doubt among attendees and IT personnel alike. Videoconferencing can be accomplished in a number of ways. As an extension of telephony, a conference call is a conference call. In traditional telephony, there is usually talk of basic conferencing in the form of ad hoc or meet-me capabilities. The minimum requirements for an audio conference is, simply put, some kind of bridging resource. The same holds true for videoconferences. The process to initiate them is identical. In an ad hoc (or instant) conference, a point-to-point call is established, followed by one party initiating the addition of the other attendees. For a meet-me conference, all parties dial a predetermined number and join an already existing bridge. Again, there is no difference when using video-capable endpoints. Where videoconferencing used to create cringeworthy responses was in the meeting room. The dreaded rolling television with a pseudo-cam on top of it and an ISDN connection that could only be initiated by individuals with specialized knowledge has become a symbol of everything the video user experience should not be. User adoption was further hampered by the inability for end users to schedule, manage, or initiate their own conference calls. The IT department was always required to accomplish any video-related resources. There was no real concept of true collaboration. Documents had to be manually distributed to meeting attendees before meeting time. Videoconferencing has become fluid and effortless using one-touch, or in some c ases zero-touch, initiation/join. These so-called immersive systems provide an in-person experience second to none. In fact, in many ways, providing just the right immersive video experience may be better than being there. Features such as Proximity, which allows meeting attendees to follow shared content from mobile devices (including screenshot and scroll-back capabilities for presentations), add a facet to meetings not previously considered a v iable possibility short of asking for the presentation to be emailed out and possibly asking the presenter to back up a slide or two. With Proximity, attendees can simply grab the pieces they want or scroll through the slides on a mobile device.

Extending Video Communications to Teleworkers As businesses search for new ways to remain profitable and reduce expenses, more and more are turning away from traditional brick-and-mortar office space for some or all of their workforce. With Cisco collaboration technologies, you can place video communications capabilities in the home or remote offices of teleworker employees. This provides the in-office experience while eliminating the need for those workers to use corporate-owned office space. The morning and evening commute now consists solely of the walk from one part of the home to the other, in many cases.

Chapter 1: Introduction to Video Communications

Teleworker architectures are by no means a one-size-fits-all proposition. The solution architecture varies along with the job function of said teleworker. Advanced teleworkers may require fully functional contact center agent capabilities, immersive video endpoints, and more. Hybrid teleworkers may spend only a percentage of time in the office and the rest of their time in the remote/home office. Other teleworkers may be fully mobile and always on the go. Each of these possibilities carries with it a specific set of highly secure and reliable architectures, which include some mix of virtual private networking (VPN), web access, voice/video capabilities, andcenter otheragents, potential technologies required desktop to fulfillvideo, the jobdesk function question. Video contact immersive TelePresence, phoneinvideo, soft phone video, streaming video, and so on are all possible requirements that can be easily implemented for any type of teleworker.

Video Contact Center The use of contact center agents is an extremely well-established means of servicing and maintaining contact with customers. In today’s world, we often encounter an increasingly negative view of contact centers. Poorly designed scripts, inefficient interactive voice response (IVR) designs, and a score of other issues have caused a revolt of sorts by customers. People calling into customer service lines now want to quickly speak to a representative, instead of trying to navigate the menus in an attempt to find what they seek. As more and more customers, clients, and peer businesses acquire video capability, it is easy to see where the video contact center agent may come into play. Using a solutionsuch as Cisco Remote Expert, customers and agents can engage in a more interpersonal discussion. This allows a level of collaboration far superior to the traditional contact center. When customers call a business, they not only get to speak to a representative, they also get to make eye contact and interact face to face, just as if they were in the same room. This proves especially valuable in high-touch or white-glove customer service-focused institutions, such as high-end banking. When large amounts of money are being deposited and withdrawn, it behooves a financial institution to provide that extra touch of technology and professionalism to make a customer feel more at ease with the decision to do business with them. Seeing and speaking to a person provides the in-person experience customers are demanding from businesses today.

Business-to-Business Video As video adoption increases and accelerates, it becomes pervasive within an enterprise. In other words, it becomes the norm. It simply becomes that which is expected in all business-related interactions. Internally, this doesn’t typically pose much of an issue because all th at is required is a video-capable endpoint and a means of reaching it across the network. Obviously, there is a bit more to it than that, architecturally. More on that as the book progresses. When business is done face to face, collaboration becomes natural. Escalation of instant messages to video calls or videoconferences can be done in a click. These same tools start to become an expectation in all dealings with peers, colleagues, partner companies, customer companies, and on down to the individual customer. Business-to-business (B2B) video is a

Call Control Call control is the component that provides the foundation of the video architecture. In essence, it is the single most important function. Without call control, there is no solution. Call control is more than just a signaling mechanism. It handles endpoint registration, dial plan, called and calling party presentation, call admission control, codec selection, and trunking operations. There is quite a bit more that goes on with CUCM, in particular. From a video architecture perspective, CUCM provides the common platform for voice and video endpoint registration and m anagement. This includes soft phone, desk phone, desktop video endpoints, and immersive TelePresence endpoints. Cisco has m ade great strides in consolidating all elements into a single call control entity to ease overall administration tasks. In addition, the instant messaging and presence (IM&P) capabilities have been rolled into CUCM from an administrative standpoint. Although the Cisco Unified Presence Server (CUPS) is still a separate virtual server, once installed, it is administered through the CUCM

1

10

CCNA Collaboration CIVND 210-065 Official Cert Guide

administrative web page. This allows a single pane of glass for call control and for IM, network-based presence, federation, and the use of Cisco Jabber on desktop and mobile devices.

Endpoints There has been a slight shift in nomenclature as it pertains to collaboration architecture. Where the collaboration architecture used to reference phones and calls, it now references endpoints and sessions. An endpoint is no longer necessarily merely a phone. The endpoint may be any phone or video device in the Cisco portfolio, be it a 3905, 8861, DX80, or MX700. From an administrative perspective, they are all identical in how they are configured in CUCM. That said, a call is no longer necessarily audio only. The term session provides a more generic descriptor while carrying the same essential connotation. With the diversity of the endpoints available comes a diversity in features that each may access and use. With call control and endpoints in play, the remaining pieces of the architecture provide modularity in functionality. Whereas call control provides a foundation, endpoints provide a means of accessing the wide array of services and applications available within the remaining architectural components. The endpoint is the face of the system as it provides the user experience. If the endpoint is difficult to use or complicated to deploy, there may be a high potential for adoption and growth problems.

Conferencing A conference is loosely defined as three or more people communicating in real time. This is a core capability of legacy voice deployments and video deployments. The ability to communicate only via point-to-point video will have a negative impact on adoption of the technology. If video is the new way, it needs to function in a similar manner to the old way, with very little, if any, learning curve. Conferencing capabilities build upon the existing infrastructure for point-to-point calls. For multiparty calls, additional resources will be required. The idea, however, is to offer the same ease of use and consistent experience regardless of how many individuals are in attendance. This is accomplished by positioning the right components within the network. These components are sized based on usage expectations and user habits. Participants can join from any standards-compliant video endpoint using standard definition (SD), high definition (HD), High Definition Plus (HD+), or a higher-end resolution known as FullHD (more on those later in the book). As adoption grows, it may well become necessary to expand the resources available for conferencing. Conferences can be classified into three types: ■

Ad hoc (instant): This is a conference that is not scheduled. It begins as a point-to-point

■

Personal (persistent): Formerly known as a rendezvous bridge, personal meeting rooms

call. Once established, one party or the other adds additional participants. are static meeting spaces defined on a per-user basis. These rooms can be allocated to executives, power users, or anyone else who requires it. Cisco Collaboration Meeting Rooms (CMR) are persistent meeting rooms that can be joined by dialing a URI and clicking a hyperlink in an invitation email (which launches WebEx) or by simply dialing

Chapter 1: Introduction to Video Communications

the pilot phone number and entering the meeting number. Like other WebEx meetings, CMR meetings can be joined from the WebEx client on any mobile device. Other terms that might describe a personal meeting room include meet-me and static bridges . ■

Scheduled (meet-me): A conference call planned in advance. The start time and resources

needed are set ahead of time. For scheduled conferences, generally, the required conferencing resources are reserved and guaranteed available at start time. As noted in Figure 1-1, conferencing uses the Conductor and TelePresence server. The TelePresence server handles the audio/video portion of the conference. The Conductor coordinates resources for conf erences. It has the ability to ca scade across bridges and allocate resources best suited for the types and needs of attending cl ients (SD/HD/HD+/FullHD, and so on) even if those resources are not collocated.

Collaboration Edge Businesses have long struggled to find the most efficient way to provide secure, reliable services to their user communities working outside of the traditional office setting. The bringyour-own-device (BYOD) movement has done little more than increase the pressure to find innovative access methodologies which provide the necessary access to services and applications while aligning to business and security policies. Collaboration edge is a new implementation of an existing technology, firewall traversal. This mechanism allows Cisco to provide mobile/remote access to teleworkers without the need for a VPN connection or additional licensing typically associated with that connection. The solution consists of two core components: Expressway-E and Expressway-C. Expressway-E acts as a traversal server for external clients, video endpoints, and so on. It will be the device also in charge of handling B2B calls and cloud connectivity (WebEx). Expressway-C acts as the traversal client. It creates outbound connections to the Expressway-E (and therefore through the firewall without need to open specific ports). The firewall traversal mechanism opens a connection through the Expressway-E, across the firewall to the Expressway-C, and then on to the other relevant components as requested by the mobile client. In Figure 1-1, the architecture shows the Express way-C on the internal network; the Expressway-E sits in the demilitarized zone (DMZ) to handle external requests coming in. The connectiv ity is established from the remote clients to the Expressway-E using Domain Name System (DNS) Service (SRV) records. When the user launches a client from a mobile device or laptop, the DNS lookup resolves the records for services required by the client application and makes contact. Registration is processed, and the user is able to log in successfully. It is suggested that the Expressway-E and Expressway-C be deployed in a highly available configuration (that is, in clustered pairs). This ensures that services are always available even when there may be network-related issues in progress. Optionally, an ISDN gateway can be deployed in support of legacy H.320 endpoints. The collaboration edge architecture also enables native interoperability with Microsoft Lync audio and video. This allows Expressway-C to support standards-compliant H.264 AVC interworking with Microsoft’s proprietary SVC implementation. Rich Media Session licenses are required on the

11

1

12

CCNA Collaboration CIVND 210-065 Official Cert Guide

Expressway-C for each session to be passed through. If Microsoft Lync clients are connecting back to the network via a Microsoft Edge server, Expressway-E is required because it provides traversal using relays around Network Address Translation (NAT) (TURN) services to Lync on behalf of the Cisco receiving endpoints.

Applications Applications available for end users are numerous. However, the applications that apply here are those mentioned in the video architecture. Specifically, these are Cisco Prime Collaboration and Cisco TelePresence Management Suite (TMS). Cisco Prime Collaboration is a suite of applications that allow provisioning, deployment, monitoring, management, and measurement of collaboration-related metrics. With Collaboration System Release (CSR) 10.x, Cisco has begun including the Cisco Prime Collaboration Standard suite of applications (for the first cluster) at no additional cost. This includes Prime Collaboration Deployment (PCD), Prime Collaboration Provisioning (PCP), and Prime Collaboration Assurance (PCA). An upgrade is available to Prime Collaboration Advanced, which adds additional functionality to PCP and PCA while adding the Prime Collaboration Analytics module. PCD is a migration/upgrade assistant module that provides for rapid installation and maintenance of CUCM and TelePresence components. It can provide a one-jump path for CUCM migration from very old versions to the latest version. It also assists in making the needed changes when CUCM IP address changes need to be made. It makes the needed changes throughout the cluster. PCP is a provisioning tool that allows the creation of business rules and work flows that allow for zero-touch deployment of new users, their endpoints, clients, and voice mailboxes. When configured to sync with Active Directory (AD), PCP detects new users. It imports them into the database and provisions all the configured services for a user of that type and in that location. PCP can also replace the use of the CUCM Administration page for dayto-day move/add/change or even troubleshooting. It all comes down to work flows and the desired degree of granularity. PCA is the monitoring, troubleshooting, and reporting module of the Prime Collaboration suite. It keeps constant track of the processes, services, call quality, and so on, just as a traditional network management suite might do. However, it is monitoring metrics such as jitter, mean opinion score (MoS), and more for voice and video calls. TMS is a server application meant to perform provisioning, configuration, directory/ phonebook functions, conference scheduling and control, endpoint/infrastructure management, and reporting for video endpoints. TMS is also used in scheduling conference rooms, allocating resources, managing CMRs, and more. It integrates with Microsoft AD and with Lotus Notes for directory and phonebook functionality. TMS also has a suite extension (TMSXE) specifically for Microsoft Outlook. This allows the creation of meetings/ conference right from the Microsoft Outlook calendar page. The TMSXE module replicates calendars between TMS and Microsoft Exchange to keep track of room resources.

Summary Video is indeed the new dial tone. Video technologies are seeing expansive growth on all fronts, be it consumer, personal, desktop, immersive, conferencing, B2B, or any other of the implementation types you might think of. It is becoming a way of life for a large percentage of the world’s population. People are simply coming to expect to be able to make eye contact in any conversation regardless of device, distance, or circumstance. The Cisco Preferred Architecture for Video guide details the basics of the architectures and what is needed to implement the capabilities discussed both in that document and in this book. This chapter addressed only the high-level video architecture and its core constituent components. It is highly recommended that anyone seeking a collaboration certification be familiar with the Cisco Preferred Architecture documents and the architectures they describe for the certification pursued.

Exam Preparation Tasks This chapter provided an overview of the architecture and components contained in the core Cisco video architecture. The information presented here is not included in the exam blueprint. Therefore, it is unlikely that you will encounter it on the exam itself. However, the information presented in this chapter is part of a prescriptive best practice for video architecture. It is necessary information for deploying and managing Cisco video solutions.

CHAPTER 2

Cisco Digital Media and Content Delivery This chapter provides an overview of the Cisco Digital Media Suite (DMS) solution. DMS is a video content creation, editing, transformation, and delivery architecture intended for use in a variety of manners, including education, sport stadiums, restaurant menus, staff training, and as many other uses that a moderately active imagination might contrive. Every question deserves an answer. The age old question “why?” comes to mind when businesses and educational institutions are first presented with DMS as a potentially useful and valuable architecture. In addressing that simple question, it is necessary to understand, at least in part, the roots of the technology. With that in mind, a small discussion of history is in order, followed by a more lengthy discussion of the DMS solution and its constituent components. Like many architectural solutions, DMS consists of a number of software and hardware components, each dependent on one another. They, in turn, make use of the underlying network and collaboration infrastructure. As the name implies, DMS is a video-based solution. As such, its traffic must be properly protected and prioritized throughout the network. A well-designed quality of service (QoS) deployment is critical to the success of any video implementation. Although QoS is beyond the scope of this chapter, it is well worth exploring and understanding. For more information on QoS, check out the following sites: ■

Foundation Topics Legacy Digital Media Architecture Early implementations of what evolved into digital media systems were largely proprietary systems meant to provide surveillance capabilities. Initial systems were watch-only systems; they lacked any capability to record and store the images being collected. This meant that someone had to be physically watching the screens at all times. As the technologies advanced, recording capabilities for audio and video started to be implemented and used. These systems were adapted for use in delivering content to televisions stationed throughout office buildings, plants, and so on. This could be used to deliver morning news relevant to the business, announcements, and so on. These systems were not attached to any external content provider, of course. All content to be presented was largely created and sourced by the entity owning the system. The “closedcircuit television” essentially signifies that the content is being sent to only a very limited set of endpoints, typically over physical media such as coaxial cable. It is the opposite of “broadcast television,” which is meant to be openly provided to all capable endpoints via over-the-air broadcast. Over time, recording capabilities evolved from reel-to-reel systems to the videocassette recorder (VCR) and then on to network-based storage capabilities. These network-based capabilities were often server-based solutions that would store content on local hard disks then push it out across a private network to proprietary display systems. With the coming of applications such as Microsoft PowerPoint and other slide-showcapable software packages, digital signage became a viable capability. These architectures were typically built upon PC-based platforms. Those PCs would be network attached in order to provide remote management and content access. They would also provide the interface to keyboard, mouse, and monitor to make local tweaks to and display the created content. The PC-based architecture has a number of significant drawbacks that really prevented its widespread use for dedicated digital signage. The cost of PC hardware, certainly, was one significant limiting factor. System administration difficulties, software costs, high power consumption, lack of failover/redundancy capabilities, and security (both physical and software related) obstacles made these solutions challenging, at best. In addition to these, the fact that many early solutions were proprietary meant that there could only be one source of content in specific formats for the solution. The lack of standards-compliant media was a huge challenge in attempting to make use of this kind of technology. The fact that many systems were closed and proprietary is no surprise. Innovation waits for no one. These types of systems were needed by businesses for a number of reasons. And, they were needed right now. The business world had no time to wait for the battles to be won and lost in order to implement the systems they needed for security, content hosting, and content delivery. Where there is a need, there is going to be someone smart enough to meet it and capitalize on it.

Chapter 2: Cisco Digital Media and Content Delivery 19

Cisco has done much of that type of innovation over the three decades of its existence. Technologies such as InterSwitch Link (ISL) for LAN Trunking, Cisco Discovery Protocol (CDP), Cisco Power over Ethernet (Cisco PoE), and Skinny Signaling Protocol (SCCP) are big examples of that kind of innovation. No standard existed to fill the needs demanded by businesses. So, Cisco created a temporary solution while the relevant standards were being ratified and put in place. Once the respective standards became a reality and ready for prime time, Cisco instituted a technology migration to those standards. ISL gave way to 802.1Q. CDP has begun a transition to Link Layer Discovery Protocol (LLDP). Cisco PoE has become 802.1af/802.1ac/801.at PoE. SCCP is giving way to Session Initiation Protocol (SIP) now that feature parity has become a reality between the two.

Streaming Video Providing access to streaming video in legacy environments was similarly fraught with challenges. Again, the problem largely goes back to proprietary formats and the absence of viable standards in video creation, encoding, transport, and delivery. During this time in the evolutionary stage of video streaming, the world was still largely server-based, rather than network-based. So, in the minds of many, servers were the network. The media and protocols used in making the servers communicate was largely irrelevant. No one single protocol had yet won the day, so to speak. Broadcast-based protocols, such as Novell’s Internetwork Packet eXchange (IPX) and Apple’s AppleTalk, were still prevalent in the majority of network architectures. TCP/IP was still a relative novelty in the view of many (non-UNIX) server administrators. At the same time, Ethernet had a number of available flavors and competing technologies. 10BASE2 (thin coaxial cable), 10BASE5 (thick coaxial cable), and 10BASE-T (twisted pair) were all in widespread use as transmission media. IBM’s Token Ring (at 4 Mbps or 16 Mbps) technology still had a significant foothold in the realm as well. Eventually, 10BASE-T won out over its coaxial cable-based cousins, and the battle came down to 10BASE-T Ethernet versus Token Ring. Ethernet eventually won that battle as well. But, it is worth keeping in mind that the technologies in use in the 1990s were a wild mix of Layer 1, Layer 2, and Layer 3 protocols as numerous communications methodologies fought for survival. Today, there is one prevalent Layer 1 infrastructure for the local-area network (LA N); a simila rly prevalent Layer 2 protocol infrastructure; one prevalent Layer 3 protocol; and a wide array of standa rds focused on communication, audio encoding/transmission, video encoding/transmis sion, and much more beyond that. The video battle still rages to a la rge degree, of course. But, it too will be settled in due time. With all the chaos in the industry, content distribution was almost entirely manual. That is, the content had to be pushed by an administrator to a server somewhere, which is then made accessible to the PC end stations actually presenting the content. In many architectures, administrators were required to manually push the content to each local PC. It all came down to just how network aware the proprietary application in use happened to be. The use of web-based services with audio, video, and other content overlay is quite new on the scene.

IPTV Large corporations were able to make use of streaming architectures within a campus environment by leveraging LAN-attached video encoders that were capable of leveraging IP-based streaming. The use of multicast technologies became a prevalent delivery mechanism during this time. Content came from a number of sources, including VCR/DVD, satellite, cable TV, and custom content recorded via video camera either at a company-owned studio or simply in someone’s office. All these content sources could be pushed through a video encoder and onto the IP network. These IP Television (IPTV) feeds could reach the PC-based endpoints or proprietary display systems deployed throughout thethey campus. However, these feeds could not typically be easily stored or archived, nor could typically be deployed in a mixed-vendor endpoint environment. This was the case even once standards-compliant streaming protocols, formats, and clients were in play.

Content Portals In the pre-YouTube world, video distribution technologies presented more challenges than solutions, it seems. During the early evolutionary phases of content distribution technologies, ease of use was not all that high on the list. The proper use of video still required an IT personnel resource. Those user-facing tools that were available were somewhat less than intuitive. As the concept of the intranet came about, network administrators began to push more and more of the capabilities out to the user community. In most cases, this amounted to a simple web page format or a wiki-type blog format that presented links to the video files and hopefully some kind of description of the file content. As the user clicked each link, the files could be accessed and downloaded. This was usually accomplished via Common Internet File System (CIFS) or File Transfer Protocol (FTP) to deliver the file to the user’s local PC. There was no means of simply embedding the video into the web page to be streamed from a central location. Resources were largely decentralized at this point. Once downloaded, a client installed on the desktop could then be used to play each file individually. unusual for a separate desktop client to be needed for each type of video formatIttowas be not played. Although the use of intranet services and wikis did offer a more streamlined means of providing content, it did not allow users to share content. In many cases, they were not allowed to upload their own content either. Each server held a different library of content (and, therefore, had to be accessed independently). This limits user interactivity, sharing, and content upload. In today’s world, content is content, and anyone can create, upload, share, and distribute it. There are obvious needs for security and protection of confidential information, of course. Those security mechanisms are certainly in place. User interfaces for these content portals are intuitive and support a wide range of software clients and hardware platforms, both static and mobile. These services are intended to provide anytime, anywhere, any device support for all content relevant to the business.

Chapter 2: Cisco Digital Media and Content Delivery 21

Cisco Digital Media Suite In DMS, Cisco provides a comprehensive set of tools that enable companies to create flexible, scalable, and easily accessible content for end users, departments, peers, customers, and more. DMS offers an all-in-one solution for webcasting, video sharing, digital signage, and IPTV applications. Making the integration of digital media into the day-to-day business flow enhances communication and changes the way we collaborate and interact with our peers, colleagues, and others. Like any other architecture, DMS includes a number of modular components. This modularity allows the creation of a custom-tailored solution based on the business needs at the time of deployment and the ability to grow, and add additional modules, as desired. The subsystems of the DMS solution are as follows: ■

Cisco Digital Signs: Digital signage subsystem that dynamically delivers content to be

displayed ■

Cisco Cast: IPTV application that allows on-demand delivery of content

■

Cisco Show and Share: Enables users to create live and on-demand content using social

media aspects such as tagging, commenting, and rating Each of these subsystems is discussed in later in this chapter. All the applications in the Cisco DMS solution work with the Cisco Digital Media Manager (DMM). DMM is a centralized web-based management portal through which all products can be administered. The DMM is also used in managing, scheduling, and publishing digital media content. Figure 2-1 shows the core components of the Cisco DMS solution. 3425 %+* 34%,) !(- %+* ./! /"012 /%0$

Figure 2-3 DMM Home Page

The DMM is the primary management interface for the Digital Signs, Show and Share, Cast, and administration of the DMM server itself. Clicking the Administration tile on the home page brings you to the Dashboard. The Dashboard provides a summary of DMPs in inventory, Show and Share server status, in addition to failover, clustering, and so on. Figure 2-4 shows the DMM Dashboard page. Along the top row of the page are additional tabs for configuration of the system and its controlled subsystems. Users can be assigned to groups and roles specific to their function, be it admin, read-only, digital signage users, and so on. This administration portal is the heart of the DMS solution. It is where configuration and troubleshooting take place, services are stopped and started, licensing is applied, and so on. If there should happen to be some failure with the DMM, the DMP functionality would not be impacted.

Figure 2-5 MXE Manual Video Upload

The process is rather straightforward. The file is uploaded via the Browse button. Once uploaded, a title is given to the video. Optionally, a description and tags can be added followed by a click of the Next button. With that done, the output formats need to be selected. Figure 2-6 shows the output format selection page.

Figure 2-6 MXE Output Format Selection

Numerous formats are available for the output video. What is shown in the figure is only a subset of the available options. Once you select the desired output formats and click the Next button, additional enhancements become available. Figure 2-7 shows the options available to enhance the video.

Based on size and scale, SnS can be deployed in fully on-premises, colocated, or distributed deployment models. SnS provides the following functions and features: ■

Workflows for flexible authoring, publishing, and reviewing

■

Multiformat file types and recording from USB cameras

■

Creation of secure video communities

■

Ability to enable commenting, rating, and word tagging

■

Highly flexible user/group management and viewing rights

■

Advanced content storage, archiving, and distribution management Seamless integration into the digital-content network

■

SnS 5.5 added a connector for Microsoft SharePoint. This allows content to be published from SharePoint to SnS. It also allows the user to surface all video from SnS directly in SharePoint. In addition to allowing for viewing of videos, it allows posting of comments directly from SharePoint.

Capture Transform Share Capture Transform Share (CSX) is a solution more so than a product. It is the grouping of TCS, MXE, and SnS as a single architecture for content recording, transcoding/formatting, and publication. As might be expected, the solution provides for video on-demand and video-streaming services. For recording, the solution uses TCS. Recording is initiated simply by placing a call to the URI of your TCS account. To end recording, simply hang up the call. Once the call is dropped, the workflow kicks in. The recording is pushed to the MXE for transcoding to any desired format and optimized for numerous playback devices. The layout can be customized based on the type of device or media format. With that complete, the content can be pushed automatically to the SnS portal or held for approval. Additional options can be added, such as bumpers, watermarks, or Pulse Analytics. Pulse Analytics is a speech- and voice-recognition mechanism that transcribes audio to text and identifies speakers in recorded content. Once a speaker is named, it will remember that speaker for future content publications. Once Pulse Analytics has completed processing a particular video, the text of the audio is available to those viewing the content. Spoken words are associated with individual speakers and made searchable. For example, if a professor records a biology class wherein the topic of conversation is plant life, the viewer can search on keywords such as “photosynthesis” or “cell wall” or anything else pertaining to the topic. If the keywords were spoken during the class session, each instance will be returned along with actionable links to the specific point in the discussion where the keyword occurs and who spoke the word. It provides a powerful tool for asynchronous student/teacher interaction or other non-real-time communication between presenter and viewer.

A Cisco end-to-end solution can be broken down into three categories: ■

Threat detection can be categorized by the physical security elements in a surveillance solution, such as cameras, motion sensors, and access control.

■

Threat monitoring is based on real-time and recorded threat-monitoring services. Such services may include door sensors and badges, fingerprint scanners or other biometric sensors, video-surveillance monitoring software, and other media management and storage components.

■

The third category of the Cisco end-to-end solution is threat response. This service includes the IPICS allowing integration with existing communication devices, whether that be a Voice over IP (VoIP), public switched telephone network (PSTN), or video collaboration solution.

Components of a Cisco Digital Media Suite (DMS) could be incorporated, as well, such as PCs, Digital Media Player (DMPs), Cisco LCD Displays, and the Cisco Digital Media Manager (DMM). All three of these services work together to offer a complete and highly effective Cisco video-surveillance solution.

Cisco Video-Surveillance Components The remainder of this chapter covers Cisco cameras and analytics, Cisco video-surveillance management software, and the Cisco media management and storage components. The Cisco video-surveillance solution can be divided into four service domains: ■

Management elements include features like central management of previously mentioned devices, operations like PTZ and camera switching, media control, distribution, and layout changes. Management can also determine where recorded media is to be stored. Storage involves compressing media when needed and using scalable storage solutions, whether that be locally attached storage or a networkattached storage (NAS) or storage-area network (SAN). Interactive view elements monitor endpoints such as operator view stations. It also contains distribution elements notifications and media store distribution.

Input and Output Devices The Cisco IP cameras include standard-definition (SD) and high-definition (HD) capabilities. They communicate using IP and standards-based interfaces and protocols such as MPEG and H.264. Cisco IP surveillance cameras also include embedded security and networking, motion detection, and video analytics. As mentioned before, Cisco Medianet offers the features PoE, automated provisioning, bandwidth optimization, storage optimization, and enhanced network security. There are four series of cameras to choose from in the Cisco

solution. Each has different capabilities to cater to the various needs of the customers. Some come in a box model, and some come in the dome model. The 6000 series comes in both box and dome models. Figure 3-3 shows box and dome cameras.

Figure 3-3 Box and Dome Cameras

The Cisco Video Surveillance 7000 series IP cameras support a 5-megapixel lens. It is an outdoor fixed HD camera in vandal-resistant housing. This series offers excellent image quality with resolutions up to 2560x1920 and PTZ support. The Cisco Video Surveillance 6000 series IP cameras support a 2.1-megapixel lens and offers HD video capability in bullet, box, and dome models. These cameras can be used indoors or outdoor and support up to 1080p30 resolutions. The Cisco Video Surveillance 4500E series IP cameras offer true HD video at 1080p, with H.264 compression. These dome IP digital cameras are designed for superior performance in a wide variety of video-surveillance applications. The Cisco Video Surveillance 3000 series IP cameras are full-functioning HD cameras with H.264 support. These dome cameras can support resolutions up to 1280x800 at 30 frames per second.

Chapter 3: Cisco Video Surveillance

Another output device is the Cisco Video Surveillance Encoder. These devices use digital signal processors (DSPs) to convert analog signal from legacy analog cameras to digital format. Encoders are an optional component of the Cisco Physical Security Multiservices Platform, and the Cisco Video Surveillance Media Server Software must be installed on the server to use them. There are two cards available offering either 16 BNC connection panel or an 8 BNC connection panel on a single card. The resolution of these capture cards is D1, with motion JPEG (M-JPEG) and H.264 support. D1 resolution is 704x480, and is the highest SD resolution available in common analog-based CCTV deployments. Additional support on these encoder cards includes RS-232 for remote PTZ control of cameras. Note that although only Cisco IP surveillance cameras are mentioned in this chapter, thirdparty systems are supported by the Cisco DMS solution. This includes third-party IP surveillance cameras and legacy analog cameras through encoders. Also, Cisco IP surveillance cameras are supported by third-party management software, as well.

Management The Cisco Video Surveillance Manager Software (VSMS) is the management and control plane for the Cisco video-surveillance solution components. Cisco VSMS is a software suite that includes the Cisco Video Surveillance Operations Manager, Cisco Video Surveillance Media Server, and Cisco Video Surveillance Virtual Matrix. These software components of the VSM are the three management software solutions that are discussed in this section. The Cisco Video Surveillance Media Server software is the core component of the networkcentric Cisco video-surveillance solution. This software is responsible for the recording, storing, and streaming of video feeds. The Cisco Video Surveillance Storage System complements the Cisco Video Surveillance Media Server software. Video can be stored in direct-attached storage (DAS), NAS, and SAN storage systems. The way it works is that each IP camera or encoder sends a single video stream to the Cisco Video Surveillance Media Server. This software is responsible for simultaneously distributing live and archived video streams to unique viewersinput over an IP network. case of multiple view requests, therequest. software replicates the video streams toInmultiple output streams, based on For archive viewing, the Cisco Video Surveillance Media Server continuously receives video from the IP camera or encoder, as configured per the archive settings. The software sends video streams to the viewer only when requested. In environments with remote branch locations, this process becomes efficient because traffic needs to traverse the network only when requested by remote viewers. Video requests and streams are delivered to the viewer by using HTTP traffic (TCP port 80) or over HTTPS (TCP port 443). The Cisco Video Surveillance Operations Manager is the core engine for the Cisco surveillance solution. It offers centralized administration of all the Cisco video-surveillance solution components and supports Cisco video-surveillance endpoints. For security purposes, it uses authentication and access management for video feeds. Application programming interfaces (APIs) can be used for third-party integration, and third-party camera and encoder support is provided. Tools available in the Cisco Video Surveillance Operations Manager include a web-based portal that can be used to configure, manage, display, and control video from any Cisco surveillance camera or encoder. Many third-party endpoints are supported as well. Tools are available to manage multiple Cisco Video Surveillance Media

that have been discussed and explains the flow of media, the communication signaling paths, and interactive views that can be used in a Cisco video-surveillance solution. The two scenarios that are discussed are the Cisco Video Surveillance Operations Manager Viewer and the Cisco Video Surveillance Matrix Viewer. When an operator is interacting with the Cisco video-surveillance software, the Cisco Video Surveillance Operations Manager software is being used through Microsoft ActiveX web browser. This traffic can use TCP port 80 (HTTP) or 443 (HTTPS). The following steps outline the process Cisco’s video-surveillance software follows to change camera views: 1.

Using this software, the operator can select which cameras need to be viewed on which displays and in what camera positions.

2.

The Cisco Video Surveillance Operations Manager then sends a signal to the Cisco Video Surveillance Media Server requesting the video feed from the selected cameras.

3.

The Cisco Video Surveillance Media Server requests video feed form the appropriate cameras.

4.

The camera sends the video feed to the Cisco Video Surveillance Media Server.

5.

The Cisco Video Surveillance Media Server using TCP, UDP, or multicast sends these views to the Cisco Video Surveillance Operations Manager.

6.

The Cisco Video Surveillance Operations Manager updates the view on the appropriate view portal stations based on the parameters selected by the operations manager. The protocol used is based on what was requested by the Cisco Video Surveillance Operations Manager.

The number of video feeds that can be shown depends on the CPU, RAM, and so on of the computer . If all the feeds are displayed, some might show as thumbnails only or mig ht even make the PC unresponsive. Note

If another Cisco Video Surveillance Operations Manager Viewer requests the video from the same IP camera, the Cisco Video Surveillance Media Server simply replicates the video stream as requested. No additional requests are made to the camera. Figure 3-4 illustrates the Operations Manager Viewer scenario.

Initially, all video communications were established using H.323 protocol capabilities. This is largely due to the fact that H.323 is quite similar in operation to ISDN, in terms of messaging, troubleshooting, and so on. H.320 is a general recommendation for running voice, video, and data over ISDN circuits. The PSTN side of the connection handled audio, albeit out of band. At this point, there is still no true central call control element; however, we do finally see the advent of true conferencing as a technological possibility, even over distance. This is accomplished largely by the rapid spread of WAN technologies throughout the globe. By keeping the traffic on-net, large corporations are suddenly able to eliminate the geographic barriers that made ISDN-based calling so expensive. A video call is generally accepted to imply a point-to-point nature. The call does not become a conference until a third endpoint is added to the call. As mentioned at the beginning of this chapter, a conference requires a bridging resource. Bridging resources can come in the form of hardware-based multipoint control units (MCUs), or they may be softwarebased MCU equivalent entities. Either way, there is a means of mixing the media and getting it to all participating endpoints. Many early adopters of videoconferencing technologies did eventually get around to investing in their own infrastructure. For those companies that were just not quite there financially, hosted MCU providers began popping up all over the place. A large percentage of these providers were productizing hosted best-effort MCU services and expanded reachability made possible by a brand-new transport option called the Internet. Multipoint conferencing technologies began to rapidly evolve in terms of reachability. With the availability of both hosted and private videoconferencing resources came the need to expand the options of who could and could not attend a videoconference. These resources would need to support any combination of ISDN-based or H.323-based connections for both audio and video participants. Obviously, the need to support the use of Internet-based endpoints revealed a somewhat significant issue regarding quality of service and reliability. Figure 4-2 shows how this expanded architecture looked in terms of transport and reachability between endpoints. In the figure, all the transport mechanisms discussed thus far are represented. Those using the Internet and WAN transport would be using H.323, whereas the PSTN-based endpoints would be making use of ISDN technologies.

In the figure, there is a distinct mix of technologies, including a gatekeeper for call control, a PBX for PSTN/ISDN connectivity, a WAN infrastructure transporting on-net video, and an MCU to provide bridging resources. The ISDN gateway is a customer premises equipment (CPE) device that provides an interworking function between the ISDN network/PBX and the IP-based endpoints, gatekeeper, and MCU.

Introducing Cisco Collaboration Solutions Cisco collaboration solutions consist of a number of architectural components. The network provides the foundation which the collaborationthe applications rely. As mentioned in Chapter 1, “Introduction to on Video Communications,” Cisco Preferred Architecture includes five subsystems within the collaboration architecture. However, from an exam perspective, the more relevant aspects of collaboration architecture include technology categories, rather than the subsystems. The technology categories include the following: ■

Unified communications: Solution components aimed at bringing together voice, video,

data, and mobile applications. This includes call control, gateways, and applications. ■

Customer collaboration: Solution components aimed at customer interaction, such

as contact center applications and voice self-service products. This typically focuses on Cisco Unified Contact Center Express (UCCX) and Cisco Unified Contact Center Enterprise (UCCE) solutions for customer interaction. ■

Conferencing: Solution components used to enable anyplace/anytime multiparty com-

munications with a focus on security, high quality, and content sharing. This includes audio and videoconferencing products, web conferencing applications, and conferencing management/scheduling tools. ■

Collaboration endpoints: These are the video and telephony desktop, mobile, and

software components used by end users to communicate. This includes IP Phones, collaboration desktop Cisco TelePresence room-based and immersive endpoints, software clients, andendpoints, Cisco TelePresence integrations. Regardless of how the Cisco collaboration solution architecture is broken down, the pieces remain fairly much the same. There is a high degree of modularity in the overall solution. Many of the pieces can be mixed and matched to fit what is right for a given business or need. The underlying foundation is the call control element. Cisco Unified Communications Manager (CUCM) is the essential glue that holds the entire architecture together. The gateways are essentially extensions of the CUCM as it controls the ports through which calls will ingress and egress. Additional flexibility in the solution is provided by the simple fact that the solution can be wholly on-premises or it can be cloud-based in the form of a hosted collaboration service (HCS). The architecture is nearly identical aside from the fact that a service provider is hosting all of the relevant pieces within their network. In an HCS solution, the only components typically on premises are the IP Phones, collaboration endpoints, conferencing resources, and gateways. The rest of the collaboration solution components are in the provider cloud infrastructure. HCS solutions are priced based on

Conferencing Conferencing ha s expanded greatly over the years to encompass more than simply bridging phone ca lls together. Audio and v ideoconferencing architectures have become more and more feature rich, allowing companies to sca le their solutions to never-bef ore-seen capacities. The scope of possibilities h as also expa nded. Conferencing now requires a much wider array of service offerings, including the traditional on-premises audio and videoconferencing, but expandi ng to include web conferencing, application integration, cloud-based confer encing options, and hybrid solutio ns allowi ng the seam less integration of bothinon-premises cloud-based confer encing resources in a single meeting. As mentioned the chapterand introduction, there are three essentia l types of conferences: ■

Instant (or ad hoc) conferences

■

Personal (or rendezvous/meet-me) conferences

■

Scheduled conferences

In all three cases, the basic requirements are the same. In the context of this discussion, they require CUCM or Video Communication Server (VCS) for call control, a conference bridge resource (hardware or software based MCU), and of course the actual video endpoints participating in the conference. CUCM or the MCU bridge resource can be either on-premises or hosted (cloud-based). The Cisco acquisition of WebEx immensely upped the standard for web/audio/ videoconferencing in a cloud-based environment. Cisco WebEx includes four centers for meetings: ■

WebEx Meeting Center:The default meeting front end for Cisco WebEx. Meeting

Center allows attendees to use audio, web, and video resources for day-to-day meetings. Content can be shared into the meeting by any authorized participant. Meetings can be recorded with the click of a single button. ■

WebEx Event Center:Allows for large-scale meetings. Tools are provided for successful

■

WebEx Training Center:Provides an education-focused, interactive environment. This

delivery of online events, including planning/promotion, event delivery, and follow-up campaign reporting.

includes video capabilities, breakout sessions for discussion, and labs. Reporting is provided on a per-attendee basis, showing participation level. (Any time WebEx is not the primary application on the screen, an indicator is placed by the attendee name and the time away from the main screen logged.) ■

WebEx Support Center:A customer support meeting interface primarily aimed at

remote desktop and content sharing for real-time IT support and customer service regardless of geographical separation. Cisco has expanded the cloud-based capabilities of WebEx services by introducing the Collaboration Meeting Room (CMR). CMR provides the capability to use cloud-based videoconferencing infrastructure rather than a company needing to purchase its own onpremises infrastructure. CMR allows the creation of user-specific, personalized WebEx meeting rooms. These rooms can be scheduled or launched instantly. If there is already an existing on-premises Cisco TelePresence implementation, a CMR Hybrid (formerly known

Whereas unified communications encompasses multiple aspects of the collaboration solution, the service domain focuses on only one aspect. The service domains of particular importance in this discussion include the following: ■

Call control: A central entity within the infrastructure that is in charge of call/session

control, dial plan, and routing decisions for setup, maintenance, transfer, teardown, and other signaling aspects associated with end-to-end communications. Call agents (a.k.a. endpoints, gateways, media services) attach to, and register with, the call control plane to make use of call-based services, web-based services, and other media-based applications ■

or services.

Endpoints: The user interface to the collaboration infrastructure. This includes desk

phones, video endpoints, immersive room systems, desktop clients, smartphone clients, tablet clients, and other advanced collaboration user systems. ■

Gateways: Connectivity to other systems and their associated network infrastructure. This

includes analog systems, PSTN connectivity, legacy PBX connectivity, SIP trunking connectivity, business-to-business (B2B) connectivity, vendor-proprietary systems, and more. ■

Media services: Audio and video media services, whether point-to-point (P2P) or multi-

point (P2MP). This includes conference bridging resources (audio/video), music-on-hold services, annunciator services, media termination point (MTP) services, audio/video recording services, transcoding services, and so on. ■

Scheduling and management:Centralized management services for collaboration end-

points, conferencing resource reservation/scheduling, videoconference layout customization, endpoint bandwidth management, and more. It is common for these systems to integrate with both e-mail services on the back end and e-mail clients at the user interface.

Call Control Of all the service domains, call control is the most important simply due to the fact that every other aspect of the Cisco collaboration architecture relies on it as the common foundation. Even the other service domains depend entirely on the existence of the call control plane to function. Over the course of the evolutionary path of both voice a nd video technologies, call control has come in numerous flavors, including both standa rds-compliant and nonstandards- compliant (that is, proprietary) forms. The technologies have come a long way since the creation of the firs t phone, the first ca mera (still/video), the first telephone switch, and so on. C all control from Cisco’s perspective now r ests squa rely upon Cisco Unified Communications Man ager. This is the case both for on-premises solutions and hosted solutions. With the acquisition of TANDBERG, Cisco greatly increased the pace of innovation in the video communications market. The heart of the TANDBERG infrastructure included the Video Communications Server. VCS can operate independently of CUCM, certainly. It has done so for quite a long time before Cisco’s acquisition of TANDBERG. VCS is a video aggregation and call processing engine for standards-based video endpoints. It provides not only for H.323 and SIP endpoints, but also interworking between the two protocols. VCS is discussed in a bit more detail later in the “VCS and Cisco Expressway” section.

70

CCNA Collaboration CIVND 210-065 Official Cert Guide

the two, often with significant manipulation of the called-party number being necessary to facilitate the call setup. This is because, traditionally, CUCM did not support URI dialing natively, where VCS has done so since its creation. The domain portion of the URI had to be stripped or added as appropriate for the call direction. URI dialing support has since been added to CUCM with version 9.x and later. Cisco has released a new twist on the VCS firewall-traversal mechanism that allows for multiple traffic types to make use of the secure connection. This new architecture is known as Cisco Expressway. Under the hood, Expressway is still VCS, albeit a slightly scaled-down version of VCS terms of total functionality. A number the former VCSendpoints functionsasare now handled byinCUCM. For example, it does not need toofactually register it has in the past. All endpoints register to CUCM. So, it is VCS made somewhat subservient to CUCM. Expressway supports video, voice, content sharing, voice mail, presence, and IM traffic over the same connections rather than simply video traffic. This feature set is known as Mobile and Remote Access (MRA). This brings to light the two additional manners in which VCS can be deployed: Expressway-C and Expressway-E. The Expressway-C and Expressway-E variations have the same essential function and deployment locations within the architecture as their VCS-C and VCS-E counterparts. Expressway-C is deployed inside the firewall, whereas Expressway-E is deployed in the DMZ or outside the firewall. External calls, business-to-business (B2B) calls, and interoperability/interworking calls still have the same requirements in terms of traversal/nontraversal calls, although they are now known as Rich Media Sessions (RMSs). Expressway architecture provides a means of allowing VPN-less access to collaboration resources to clients and endpoints outside the network. Gone are the days wherein a virtual private network (VPN) tunnel was required on each device that wanted to access corporate collaboration services. Expressway provides secure firewall traversal and line-side support for CUCM registrations. Expressway is also the mechanism that allows the use of the CMR Hybrid capability. Figure 4-7 shows how the Expressway architecture ties into the Cisco Preferred Architecture for collaboration. Note that not all endpoints are supported with the MRA functionality. At present, the 7800 series, 8800 series, and EX and DX series endpoints are supported for external connectivity. In addition, the newer lines of SX, MX, and IX series TelePresence endpoints are supported .

74

CCNA Collaboration CIVND 210-065 Official Cert Guide

For audio conferencing, CUCM has some default software conference bridging capabilities built in. If greater scale is needed, a hardware conference bridge resource consisting of digital signal processors (DSPs) is required. A Cisco ISR conference bridge will contain some number of Packet Voice Digital Module (PVDM) resources. The current generation of ISRs (2900/3900/4400 series routers) is using PVDM3 modules. PVDM3 modules contain between 8 and 256 DSP channels. These resources are registered to CUCM as a conference bridge resource and those resources invoked when required. PVDM3 modules can also handle some degree of videoconferencing, but they are not necessarily optimized to do so. Note that although the older PVDM2 hardware can be used in these ISRs (via installation in a network module such as the NM-HDV), the coexistence of PVDM2 and PVDM3 resources in a single chassis is not supported. If both are detected, the PVDM2s will be shut down. Cisco TelePresence MCUs are hardware resources specifically created to deal with videoconference bridging. MCUs come in ma ny shapes and sizes depending on the number of conferences, number of attendees per conference, resolution desired, and desired video codec support. The hardware can support multipoint collaboration up for full highdefinition (HD) video at 720p60 or 1080p60. Th is includes high-density support for various conference views, including continuous presence and picture-in-picture (PIP). These hardware resources also support multiple fo rmats a nd adaptive rate matching to provide the best possible experience to a wide array of standa rds-compliant endpoints, be they H.323 or SI P. The hardware MCU is giv ing way to virtua lized resources in the form of the Cisco TelePresence Server (CTS). The CT S can be hardware based or software bas ed. The hardware-based version is essentially a vi rtual ser ver running on a blade in an MCU chassis . CTS supports conferencing services for both H.323 and SIP endpoints as long as they are standards compliant. T he software version can run on a VMware ESXi host on nearly any supported hardware platform. The Cisco Virtual TelePresence Server (VTS) is a virtualized appliance for extremely highdensity videoconferencing. This includes enhanced view modes, multiscreen, active presence, multivendor interoperability, and multistream. Multistream is a new Cisco feature that allows the use of multiple screens both for videoconference and content sharing. Another aspect of media services for Cisco videoconferencing is the Cisco TelePresence Content Server (TCS). TCS is a software-based virtual appliance that provides recording, live streaming, and on-demand sharing of videoconference content. The content can then be distributed to any PC or portable media device, or it can be posted to a Cisco Show and Share portal. The recording function can be invoked manually, scheduled as a videoconference resource to automatically record the call and all shared content, or it can be invoked for every call. To invoke the TCS manually, the URI of the TCS is simply conferenced into the call. Cisco TCS supports the use of Cisco video endpoints or any standards-compliant H.323 and SIP video endpoints. It can connect easily to Cisco MCU resources and is tightly integrated with Cisco’s scheduling and management platform.

Chapter 4: Cisco Collaboration Overview

75

Note When interworking between H.323 and SIP endpoints is required, including

the use of the MCU, CTS, VTS, TCS, and so on, either Cisco VCS or Cisco Expressway is necessary to provide that functionality. When VCS is in play, a traversal license is used for each H.323 endpoint. For Expressway, an RMS is used.

Scheduling and Management The scheduling and management of Cisco video endpoints and conference resources is performed primarily by the Cisco TelePresence Management Server (TMS). TMS is a Microsoft Windows Server-based software package geared specifically for providing a web browserbased interface (using Microsoft Internet Information Services and the .NET Framework) to the video units, available resources, and more. The Microsoft Windows Server installation can be virtualized or installed on a bare-metal server. Obviously, Cisco prefers the use of Cisco UCS platforms, but the only real requirement is that the Microsoft Windows Server and its hardware platform meet the required specifications. TMS offers the capability to control and manage multiparty conferences, infrastructure, any standards-compliant endpoints, and more. This includes feature augmentations such as one-button joining of a meeting. Shortly before the scheduled start time of the meeting, a button shows up on the video endpoints scheduled to join a particular conference. At meeting time, a participant merely touches the button to join or initiate the conference. TMS integration with Microsoft Exchange and Outlook combine to provide a flexible, easy interface for quick conference scheduling and resource booking options. On the back end, TMS can integrate with Microsoft Exchange for scheduling through Microsoft Outlook clients. From a user perspective, an installed plug-in allows the use of an intuitive scheduling tool right from an end user’s Microsoft Outlook client. The one-button-to-push meeting access feature is available in TMS 13.1 and later.

CHAPTER 5

Cisco IP Phones, Desk Endpoints, and Jabber Overview To simply state that the Cisco endpoint portfolio is extensive and diverse is an immense understatement. The portfolio has evolved greatly since the first Cisco IP Phones were made available after the Cisco acquisition of Selsius in 1998. At that time, the true advance in technology was the fact that the phone was an Ethernet-connected device running a TCP/IP stack and capable of providing basic telephony features. A possibly-not-so-well known reference to Selsius remains in the system to this day. When adding endpoints to the Cisco Unified Communications Manager (CUCM), devices are shown with a device name similar to this: SEP000CABCDEF12. The hexadecimal portion is the Media Access Control (MAC) address of the device being added. The SEP stands for Selsius Ethernet Phone. Cisco has slowly started to move away from differe ntiating IP Phones, software-based clients, desktop video endpoints, a nd immersive TelePresence room-based video endpoints. In the past, the distinction was i mportant. Now the lines are blurring. These endpoints all have similar cha racteristics at the most basic levels and can be managed in a nearly identical manner. It seems that video has become an increasingly vital means of communication. This means that video capabilities must move from that one conference room or the executive board rooms into the masses. Every device must allow people to communicate in the manner of their own choosing. So, IP Phones, whether video capable or not, are simply collaboration endpoints. Whether the device in question is an IP Phone, software client, desktop video endpoint, or an immersive video endpoint in a conference room, it is simply a collaboration endpoint. Making a video call is now easier than making a traditional voice-only call. This chapter focuses on the Cisco IP Phone portfolio, collaboration desk endpoints, and the Cisco Jabber soft client (in its various forms). But, remember: They are all simply endpoints.

Foundation Topics Cisco IP Phone Portfolio The Cisco IP Phone portfolio consists of a rather wide array of options and feature sets. This diversity of features allows flexibility in deployment based on the needs of the individuals using the phone and the phone’s general purpose (lobby phone, break room phone, conference room phone, and so on). There is no one-size-fits-all mindset when it comes to collaboration technologies. Different users will have different needs/desires in how and where they choose to communicate. The focus rests squarely on creating the best user experience regardless of the devices in question. This section covers the following Cisco IP Phone models: ■

The order of discussion is merely based on numeric value of the series rather than form, functions, or features. The most up-to-date information about all Cisco collaboration endpoints is available here: http://www.cisco.com/c/en/us/products/collaboration-endpoints/index.html

Cisco 3900 Series Phones The 3900 series currently contains only the 3905 model as of the time of this writing. Its predecessors, the 3911 and 3951, were retired in 2010. So, there is no real need to cover them here. The 3905 is an entry-level, single-line, SIP-only handset. It addresses the need for basic dial tone at a very cost-effective price point. It is a single-line device, although it does support call-waiting. It has a small 128x32 pixel monochrome display but no programmable soft keys. Therefore, it does not support XML applications. It is Class 1 Power over Ethernet (PoE) capable or can use an external power supply. It has an integrated 10/100 switch and speakerphone as well. Figure 5-1 shows the 3905 model phone.

Figure 5-1 Cisco 3905 IP Phone

As seen in the figure, there is a Message Waiting Indicator (MWI) in the top-right corner. It has eight fixed feature keys that provide access to several functions. The buttons just below the display include a Previous button (to go back one menu level), up and down navigation buttons, along with a Select button and a Settings button for phone configuration. Just below the navigation pad is a row of three feature keys. These keys, from left to right, are Redial, Transfer, and Hold/Resume. Below the keypad is an additional row of buttons for Mute, Volume Control, and Speakerphone. Table 5-2 provides a feature overview of the 3905 IP Phone.

7925G/7925G-EX/7926 IP Phones

The 7925G, 7925G-EX, and 7926 models are 802.11a/b/g wireless handsets. They are hermetically sealed to avoid contamination by dust, liquids, and so on The exterior is coated in a rubber casing to aid in handling and provide some drop protection. These handsets meet U.S. military 810F standards. Each of the models supports Bluetooth 2.0 with Enhanced Data Rate (EDR) hands-free profile. Also built in is a button for push-to-talk functionality that can be enabled via XML application integration. One of the more interesting additions to these handsets is the introduction of an on-board Java virtual machine, which allows the handset to run Java MIDlets locally. This allows for customized content/information to be presented to the 2-inch color screen. So, why choose one model over the others? Up to this point, they each seem relatively similar in form and function. The differences are somewhat based on the intended use of the phone and the environment in which it will be used. Figure 5-3 shows the 7925G model.

Figure 5-3 Cisco 7925G Wireless IP Phone

The 7925G is the general-purpose handset model and is the most widely deployed of the three. The 7925G-EX is ruggedized and built for hazardous environments. Its bright yellow color makes it stand out in any environment. It is Atmospheres Explosibles (ATEX) Zone 2 certified for use around hazardous gases, chemicals, and other potentially explosive environments. Figure 5-4 shows the 7925G-EX handset sitting in an optional speakerphone/ charger cradle (compatible with all three models).

The 7926G has a built-in 2D image barcode scanner. This is useful in any environment wherein inventory/assets need to be tracked. The 2D barcode scanner is not a laser-based scanner. It uses light emitting diodes (LEDs) to illuminate the target barcode and takes a picture of it, which is decoded by the phone. The resulting information is then relayed to a customer/partner developed backend system application for processing/storage. The 7926G looks identical to the 7925G in almost every way. As mentioned, the only real difference is the barcode scanner situated in the top of the handset. Figure 5-6 shows a top-down view of the handset to detail the barcode scanner.

For shared handset environments, a multicharger dock is also available. The multicharger dock can hold/charge six phones at a time. 7942G/7962G IP Phones

The 7942G and 7962G IP Phones may be the two most deployed phone models in the Cisco IP Phone portfolio at present. They are significant evolutionary steps over their predecessors in that they brought wideband audio and Internet low bit rate codec (iLBC) into widespread production. Each has a 4-bit grayscale display and dynamic backlit tricolor buttons (green/yellow/red for line status) for line appearances, speed dials, busy lamp field (BLF), intercom, or application use. The 7942 has two of these buttons; the 7962 has six. These phones can be used with either SCCP or SIP. Figure 5-6 shows the 7942G IP Phone.

The lower-right quadrant of the phone includes nine buttons: ■

Messages: Provides easy access to voice mail

■

Settings: Provides access to phone customization, configuration, and troubleshooting

features functions ■

Directories: Provides access to corporate and local directories and configured speed-dial

entries ■

Services: Provides access to XML and Java applications such as Extension Mobility

and speaker ■

Headset: Provides headset hookswitch control when a headset is attached

■

Mute: Mutes the handset or speakerphone microphone

■

Speakerphone on/off: Activates or deactivates the speakerphone function

One additional button is the blue up/down navigation pad located in the center of the phone. This button is used to scroll through available options within the phone menus or to scroll through and select individual calls when multiple calls are active. The 7962G supports the use of up to two 7915 expansion modules (a.k.a. sidecars). The first expansion module can piggyback off of the PoE supplied to the phone by the access switch or external power supply. Note The 7915 is not supported with the 7942G.

The second expansion module can be used only by adding an additional external power supply. The expansion modules easily mount to the right side of the phone, or each other, in the case of multiple expansion modules. The adjustable footstand of the phone has to be removed and replaced with a fixed footstand that supports the form factor of both the phone and the expansion modules. Figure 5-8 shows the 7915 expansion module.

Chapter 5: Cisco IP Phones, Desk Endpoints, and Jabber Overview

Figure 5-8 Cisco 7915 Expansion Module

As shown in the figure, each 7915 provides 2 display page buttons (under the display) and 12 dynamic tricolor backlit buttons identical in function to the 6 buttons on the phone itself. This configuration allows each expansion module to provide a total of 24 buttons. In keeping with consistency of look and feel with the 7962G, the 7915 has a 4-bit, highresolution, grayscale display and is not backlit.

7945G/7965G/7975G IP Pho nes

The 7945G, 7965G, and 7975G add to the functionality of the 7942G and 7962G by providing 16-bit color, backlit screens, and Gigabit Ethernet capabilities. As such, these phones require additional power, bumping the power need up to Class 3 compared to the 7942G and 7962G models. To mitigate some portion of the increased power draw, these phones have a Display button placed to the right of, and in line with, the row of programmable soft keys running along the bottom of the screen. These phones can be configured with screen timeout values. When the phone is idle for an extended period of time, the screen blanks out to reduce power usage. When this happens, the display button illuminates (green). When the phone rings, or is taken off hook, the screen automatically wakes. Pressing the Display button manually wakes it. The 7945G and 7965G were developed with a similar form factor to the 7942G and 7962G. Like their cousins, these phones support either SCCP or SIP. Figure 5-9 shows the 7945G model. It is clear from the figure that the button layout is nearly identical with the exception of the center button. The 7945G has two programmable line buttons; the 7965G has six programmable line buttons. Of course, those line buttons can be configured as lines, BLF, speed dial, intercom, or application keys. Whereas the 7942G and 7962G have an up/down navigation pad, the 7945G and 7965G have a four-way navigation pad with a Select button (signified by a check mark) in its center. Figure 5-10 shows the 7965G model.

Figure 5-9 Cisco 7945G IP Phone

Figure 5-10 Cisco 7965G IP Phone

The 7975G IP Phone adds an additional dimension of functionality with touchscreen capabilities. The touchscreen display is larger than the displays on the 7945G and 7965G. In addition, the 7975G phone has eight programmable line buttons and five programmable soft key buttons. Due to those factors, the form factor on the 7975G is slightly larger than the 7945G and 7965G. Figure 5-11 shows the 7975G phone.

support SCCP. Cisco has introduced some interesting new features in this line. These phones are a new design, from the bottom up, while maintaining a look and feel reminiscent of its predecessors. The lines are sleeker, yet very obviously influenced by the iconic 7900 series phones. They were built with a focus on providing a highly intuitive user experience. Each has been hardware enhanced for high-quality wideband voice and increased echocancellation capabilities. In addition, vibration-isolation techniques have been employed on the speakers and microphones to ensure an optimal communication experience. The 8800 series phones include both audio-only and video-capable models. For video communications withthe thedesk audio-only models, the Jabber clientThat on the desktop can beIPused for video, while phone itself handles the audio. said,user nearly any Cisco Phone can be video enabled in this manner. There are seven phone models in the l ine, six desktop ha ndset models and one conference room phone model. The series includes the 8811, 8831, 8841, 8851, 8861, 8845, and 8865 phones. Cisco 8811 IP Phone

The 8811 phone is the entry-level model of the line, but it does not necessarily have the limitations one might assume in an entry-level handset. This phone does have support for headset integration (RJ-9 and AUX ports) and is equipped with a Gigabit Ethernet port/ integrated switch. It is a Class 2 PoE device, supporting 802.11af/at power along with Cisco EnergyWise. It also has an integrated Secure Sockets Layer (SSL) virtual private network (VPN) client. This makes it ideal for both knowledge workers and teleworkers alike. The 8811 is the only model featuring a monochrome display. The display is a 5-inch 800x480 monochrome display with white backlighting. Figure 5-13 shows the 8811 phone.

Figure 5-13 Cisco 8811 IP Phone

Chapter 5: Cisco IP Phones, Desk Endpoints, and Jabber Overview

97

As shown in the figure, the phone combines soft keys and fixed function keys to keep the most commonly used features at your fingertips. This phone includes 5 line keys (multiple calls per line key), 4 programmable soft keys (context sensitive), a five-way navigation pad, and 12 fixed function keys (Messaging, Directory, Services, Volume, Hold/Resume, Transfer, Conference, Mute, Speakerphone, Headset, End Call, and Return [or backing up one menu level in the phone’s menu structure]). Cisco 8831 IP Phone

The 8831 is purpose built for conference rooms. It consists of a base speaker unit, a wired control panel with dial pad, and up to two microphones. These microphones are available in both wired and wireless configurations. The wireless microphones are rechargeable and come with the charging base. Two 8831 speakers can be daisy-chained together to reach across a large conference table. This avoids the age-old problem of a large table with two conference phones dialed into a meeting. In such meetings, the coordination of muting/ unmuting each phone as participants with to speak becomes cumbersome, at best. With the 8831, a single phone can provide 360-degree coverage in the largest conference room. When daisy-chaining speakers, wired microphones must be used. Figure 5-14 shows the 8831 phone.

Figure 5-14 Cisco 8831 IP Phone

The 8831 is a full-duplex, wideband audio speakerphone. As with the other models in this series, it is a SIP device. It has a 10/100 Ethernet port for connectivity and is classified as a Class 3 PoE device. The 396x162-pixel monochrome display is white backlit. The control panel with dial pad has four programmable soft keys and one line key. It also contains fixed feature keys for Volume Control, Mute, Speaker On/Off, and a navigation pad. The base station speaker and microphones each include a mute button as well. Cisco 8841/8851/8861 IP Phones

These three models are combined into a single section primarily because they look nearly identical. In terms of what is visible from the figures included herein, there is little visible difference, if any, from a frontal view. In fact, the only real difference in appearance from the 8811 is the monochrome display, whereas these three models have color displays. For

5

98

CCNA Collaboration CIVND 210-065 Official Cert Guide

that reason alone, front-view pictures of all three models are not included as has been the case up to this point in this chapter. They do have significant feature variation, however. But, first, let’s focus on what they have in common. Figure 5-15 shows an 8841 phone.

Figure 5-15 Cisco 8841 IP Phone

All three models include a 5-inch high-resolution (800x480) Wide Video Graphics Array (WVGA) color display. None of these, however, are touchscreen displays. The phones have aany 10/100/1000 switch andmodel are SIPhas devices. there is calls no SCCP support of the 8800integrated series models. Each 5 line Again, keys (multiple per line key), in 4 programmable soft keys (context sensitive), a five-way navigation pad, and 12 fixed function keys (Messaging, Directory, Services, Volume, Hold/Resume, Transfer, Conference, Mute, Speakerphone, Headset, End Call, and Return [for backing up one menu level in the phone’s menu structure]). All the phones support 802.11af/at PoE and Cisco EnergyWise. The similarities come to a somewhat abrupt end there. The 8841 is a Class 2 PoE device, the 8851 is a Class 3 PoE device, and the 8861 is a Class 4 PoE device. The reasons for the differences in power draw are due to newly introduced features and ports on the phone itself. Figure 5-16 shows a rear view of the 8841 phone. This is primarily for reference to illustrate the differences discussed momentarily.

Chapter 5: Cisco IP Phones, Desk Endpoints, and Jabber Overview

99

5

Figure 5-16 Rear View of the Cisco 8841 IP Phone

These phones come in either charcoal or white color options. The figure shows the white phone model primarily because the contrast makes the port differences more evident. In Figure 5-16, visible ports include, from left to right, power, network, switch port, AUX, headset, and handset. Also note that there are no ports along the left outer edge of the phone. The 8851 and 8861 have added Bluetooth functionality in support of a feature known as Intelligent Proximity. Intelligent Proximity for desk phones allows the pairing of the phone to a smartphone. This allows the same functionality at the desk phone as one might see in a modern car with Bluetooth functionality. It will synchronize contacts and call history and provide voice/video connectivity. When the smartphone rings, the desk phone rings along with it and provides answer options. A call in progress can be moved back and forth from the desk phone to the smartphone by selecting a different audio source on the smartphone when a call is in progress. This allows the use of the superior acoustical resources of the desk phone over that of the smartphone. Another added feature is USB support. The 8851 has one USB port intended for use in charging smartphones. Figure 5-17 shows the rear view of the 8851 phone.

100

CCNA Collaboration CIVND 210-065 Official Cert Guide

Figure 5-17 Rear View of the Cisco 8851 IP Phone

Comparing the figure to Figure 5-16, the only visible difference is the outer left edge where a USB port has been added. The 8861 has two USB ports. One of those ports, like the 8851, is for smartphone charging; the other is for charging tablets. Figure 5-18 shows the rear view of the 8861 phone.

Figure 5-18 Rear View of the Cisco 8861 IP Phone

Chapter 5: Cisco IP Phones, Desk Endpoints, and Jabber Overview

101

Like the 8851, the 8861 has the side USB port. But, an additional USB port has been added on the back of the phone as well. This USB support, on the 8851, 8861, and 8865, is also used in providing support for key expansion modules (KEM). The 8800 KEM has a 4.3–inch, 480x272-pixel, backlit graphical display. The font size has a small and large configuration option for added customization of key labels. The 8851 supports the addition of two KEMs, whereas the 8861 and 8865 support three. The first KEM attaches to the side of the phone using a special interface port and the USB port. Each KEM contains an identical port configuration on both sides. In Figures 5-18, the left outer edge is the KEM connection location. Figure 5-19 shows the 5-17 8800and KEM.

5

Figure 5-19 Cisco 8800 IP Phone Key Expansion Module

Each KEM contains 18 physical keys and 2 page keys, for a total of 36 additional keys per module. This means that the addition of KEMs can provide up to an additional 72 line/feature keys for the 8851 and 108 line/feature keys for the 8861 and 8865 phones. Cisco 8845/8865 IP Phones

The two newest phones in the Cisco IP Phone portfolio are the 8845 and 8865 models. These two models bring integrated 720p HD video to the desk phone. These phones use the same basic form factor as the rest of the 8800 line. However, some modifications make them slightly differ in look, namely the addition of the small camera at the top of the display. This is not an add-on camera, such as that used with the 9971, for example. It is a true

102

CCNA Collaboration CIVND 210-065 Official Cert Guide

integrated HD camera. The video calling features include a selectable position picture-inpicture (PIP), view swap (remote end or self-view), minimize video, self-view video, and video UI and conference/transfer initiation. There is also a privacy shutter on the integrated camera to stop the video broadcast. Both models include 10/100/1000 Ethernet capabilities with an integrated switch. Like the 8841/8851/8861 models, these include a 5-inch high-resolution display at 800x480 resolution, 5 line keys, 4 programmable soft keys, and 12 fixed feature keys. Both endpoints also include support for Bluetooth connectivity for headset and Intelligent Proximity pairing to smartphones. This isphones. the same Intelligent Proximity functionality as has been discussed with the 8851 and 8861 Figure 5-20 shows the Cisco 8845 IP Phone.

Figure 5-20 Cisco 8845 IP Phone

The 8865 has been enabled with more a somewhat more advanced f eature set than the 8845. This includes the additio n of USB ports for charging of sm artphones (side USB port) and tablets (back USB port) in the same ma nner as the 8861’s configuration. Ref er back to Figure 5-18 for the port layout. In addition, the 8865 has been configured to include wireless networking support for 802.11a/b/g/n/ ac environments where w ired network connectivity may not be available bu t HD video calling cap abilities are desired. In the absence of PoE, a Power Cube 4 is required to power the phone. Another added capability of the 8865 is support for the use of up to three 8800 series KEMs . Figure 5-21 shows the Cisco 8865 IP Phone.

Chapter 5: Cisco IP Phones, Desk Endpoints, and Jabber Overview

Figure 5-21 Cisco 8865 IP Phone

Looking at both Figure 5-20 and Figure 5-21, these phones look nearly identical; however, there are aesthetic differences evident upon closer examination. The 8865 is essentially an 8861 with added video. Both phones, video aside, are identical from a feature perspective. The 8845 does not easily map to its counterpart handset, the 8851, however. The 8845 does include Bluetooth and Intelligent Proximity, but it does not include the USB or KEM support available to the 8851.

Figure 5-22 Cisco 8945 IP Phone

The 8945 includes 4 tricolor LED line/feature keys, 4 programmable soft keys, and 12 fixed function keys. The fixed function keys include Applications, Directories, Messages, Volume Control, Headset, Speakerphone, Audio Mute, Video Mute, Transfer, Conference, Redial, and Hold/Resume. As an added feature, Bluetooth support has been built in to this model for use with hands-free headsets. However, unlike the 8851/8861, the Bluetooth support on this model does not have Intelligent Proximity. The body of the 8945 is built from reground and recycled plastics, making this an ecofriendly and rugged phone. A Class 3 PoE device, the 8945 has a 10/100/1000 integrated switch and supports both SCCP and SIP for line-side signaling. Adding to its green capabilities is a deep sleep option, which cuts the power consumption down to less than 1 watt during off-hours. Cisco 8961 IP Phone

The 8961 is a collaboration endpoint intended for use by knowledge workers, managers, and executives desiring desktop voice communication capabilities. Designed with ergonomics in mind, the 8961 has clean, uncluttered lines and an intuitive user interface. The 5-inch

640x480-pixel TFT display is backlit and has an antiglare finish and an adjustable viewing angle. It is designed to enhance the user experience when using multimedia applications, such as XML or MIDlet applications developed both by Cisco and by third-party developers. Figure 5-23 shows the 8961 IP Phone.

5

Figure 5-23 Cisco 8961 IP Phone

This phone features 5 programmable line/feature keys, 4 programmable soft keys, and 12 fixed feature keys. It has an integrated 10/100/1000 switch built in. The 8961 supports only SIP for line-side signaling and is classified as a Class 4 PoE device. It has a USB port for use with wired headsets or the base station of wireless headsets. Like the 8945, the 8961 is manufactured from reground/recycled plastics. It also supports the deep sleep mode feature for off-hours power saving. It also supports Cisco EnergyWise implementations. The 8961 uses the Cisco Unified IP KEM; however, unlike the previously discussed phone models, only one KEM can be attached to this phone. Figure 5-24 shows the KEM for the 8961 phone. This same KEM is also used with the 9900 series phones, discussed in the next section.

108

CCNA Collaboration CIVND 210-065 Official Cert Guide

Figure 5-24 Cisco Unified IP Key Expansion Module

The KEM has 18 tricolor LED buttons for lines/features and 2 page buttons, adding a total of 36 additional line/feature buttons to the phone’s capacity. The KEM has a 480x272-pixel color, backlit, antiglare display. It is line-powered when the phone is using 802.3AT PoE or can be powered by a Power Cube 4 external power supply.

There are also 4 programmable soft keys in a row just beneath the display as well as 12 fixed-function feature keys on the phone itself, arrayed around the keypad. Additional features added to the 9951 phone include support for Bluetooth 2.0 for wireless headset support. Two USB ports are also on board for use with wired headsets. Whether wired or wireless, the phone supports high-definition voice for increased sound clarity. The 9951 includes an integrated 10/100/1000 switch port to facilitate the connection of a wired workstation to the phone. This phone does support the use of XML-based applications and services and the use of up to three KEMs. The first KEM is powered via the PoE provided by the access layer switch. Additional KEMs require the use of external power. Cisco 9971 IP Phone

The 9971’s 5.6-inch, 24-bit, 640x480-pixel TFT display is backlit and has an antiglare finish and an adjustable viewing angle. Unlike the display of the 9951, the 9971 display is a touchscreen. The display supports the use of both left-to-right and right-to-left language deployments as needed in global deployments. It has 12 tricolor LED keys arrayed in 2 columns of 6 on either side of the display. Six of these keys are programmable for use with telephony functions such as line keys, speed dials, BLF, call park, call forward, and so on. The other 6 keys are session keys that can be tied to applications, services, or other similar functions. Figure 5-26 shows the 9971 IP Phone.

Like its 9951 smaller counterpart, the 9971 phone includes support for Bluetooth 2.0 for wireless headset support. Two USB ports are also on board for use with wired headsets. Whether wired or wireless, the phone supports high-definition voice for increased sound clarity. The 9971 includes an integrated 10/100/1000 switch port to facilitate the connection of a wired workstation to the phone. The 9971 extends the functionality of the 9951 with an additional line and session key and the addition of an 802.11 a/b/g wireless network radio. Note that when the phone is deployed wirelessly, the integrated 10/100/1000 switch port cannot be used. This phone does support the use of XML-based applications and services and the use of up to three KEMs. The first one is powered via 802.3AT PoE provided by the access layer switch. Additional KEMs require the use of external power. Table 5-9 provides an overview of the features of the 9900 series phones. Table 5-9 Cisco 9900 Series IP Phone Features F e at ure/ Fun c t i on

15 degrees from vertical. The accompanying TelePresence Touch 8 pad allows for simple, intuitive operation of the endpoint. In the spirit of providing a face-to-face communication experience, the unit includes an integrated microphone along with two speakers built in to the front of the display panel. It also includes a handset for times when private audio communication is desired. The use of an external headset and microphone is also supported via 3.5-mm jacks built in to the unit. The EX60 includes a TelePresence PrecisionHD camera that can be used as a document camera by moving it to point straight down. When it detects that it is being moved into vertical position, it flips the picture sobuilt that in both parties seeThis the allows document right-side up. The camera also has a privacy shutter to the bezel. the local user to control whether the far end can see him/her. It is the video equivalent of an Audio Mute button. The camera has a 1/3-inch 2.1-megapixel sensor, allowing a 50-degree horizontal / 29-degree vertical field of view. Beginning with Cisco Unified Communications Manager 8.6, the EX60 can be registered as a SIP endpoint in a similar fashion to any other Cisco IP Phone. This was a crucial step in merging the legacy TANDBERG Video Communications Server (VCS) architecture with the vision and future of a single Cisco collaboration call control foundation. Although the endpoint can be used with either VCS or CUCM, future development efforts will be primarily focused on CUCM-related functionality. Figure 5-27 shows the Cisco TelePresence EX60.

Regardless of deployment mod el, the EX60 supports H.261, H.263, H.263+, and H .264 video standards. W hen it is not filling its role as a v ideo endpoint, it can ser ve as a nicely sized second monitor for a single DVI-I attached workstation or laptop. Through this connection, content can be shared into the video stream at 720p. The EX60 is supported with Cisco TelePresence Version TC4.0 and later or TE6.0.

Cisco EX90 The EX90 is really the big brother to the EX60. In both form and function, it is quite evident that they share a common ancestry. Like the EX60, the EX90 includes an integrated 10/100/1000 switch to facilitate both network and workstation connectivity via a single network drop. It has a 24-inch HD display capable of 1920x1200 resolution and 5-ms response time, and provides a 160-degree viewing angle. As a video communications endpoint, it supports resolutions of 1080p30 and 720p60. The tilt of the unit can be adjusted within the range of 5 to 15 degrees from vertical. The accompanying TelePresence Touch 8 pad allows for simple, intuitive operation of the endpoint. In addition to the integrated microphone and dual front speakers, the EX90 also has a built-in subwoofer for higher sound quality. It also includes a handset for times when private audio communication is desired. The use of an external headset and microphone is also supported via the dual USB ports or 3.5-mm jacks built in to the unit. The EX90 includes a TelePresence PrecisionHD camera that can be used as a document camera by moving it to point straight down. When it detects that it is being moved into vertical position, it flips the picture so that both parties see the document right-side up. The camera also has a privacy shutter built in to the bezel. Unlike the EX60, the EX90 has an optical, motorized zoom feature. The camera has a 1/3-inch 2.1-megapixel sensor, allowing a 45- to 65-degree horizontal / 40- to 27-degree vertical field of view, depending on the zoom factor. Another key difference between the EX60 and EX90 is support for a feature known as multisite. EX60 does not support it, whereas EX90 does. This feature is enabled through the addition of an option key in the TC cod e. Like the EX60, beginn ing with CUCM 8.6 , the EX90 can be regis tered as a SIP endpoint. As mentioned, while the endpoint can be used with either VCS or CUCM, future development ef forts will be primari ly focused on CUCM-related functionality . Figure 5-28 shows the Cisco TelePresence EX90 used in an education setting.

Regardless of deployment model, the EX90 supports H.261, H.263, H.263+, and H.264 video standards. As with its counterpart, it can serve as a nicely sized second monitor for a DVI-I or HDMI attached workstation or laptop. Through this connection, content can be shared into the video stream at 1080p. The EX90 also has additional capabilities including HDMI in, HDMI out (dual display option), as well as audio in/audio out (3.5-mm jack on rear panel). The EX90 is supported with Cisco TelePresence software version TC3.1 and later or TE6.0. Table 5-10 provides an overview of the features of the Cisco EX Series Endpoints.

Cisco DX650 The Cisco Desktop Experience line of endpoints began with the DX650. Two additional endpoints have subsequently been added to the line: DX70 and DX80. Only the DX650 is covered at this time. The DX650 is an Android OS (Jellybean)-based collaboration endpoint with a 7–inch, backlit, widescreen Super Video Graphics Array (WSVGA) capacitive touchscreen LCD with 1024x600 pixel resolution. The display can tilt between 5 degrees forward to 25 degrees backward to allow for the optimal viewing angle. An integrated 1080p capable camera, with privacy shutter, is also included. The camera has a 75-degree vertical / 67.4-degree horizontal field of view. It supports HD voice and video communications, as well as an extensive list of applications. This includes Cisco applications, such as Jabber IM and Presence, WebEx Meetings, and more, in addition to applications available on the Google Play Store, such as Pandora, Netflix, and yes, Angry Birds. Access to these applications can be tightly controlled via the CUCM administration web application. Figure 5-29 shows the Cisco DX650.

Figure 5-29 Cisco DX650

Chapter 5: Cisco IP Phones, Desk Endpoints, and Jabber Overview

117

First and foremost, the DX 650 is a SIP- based collaboration endpoint. It has a visua l telephony and messagi ng interface, favorit es list right on the desktop, and the abil ity to perform directory searches. It supports both numeric and URI dialing features. HD video support includes H.264 and advanced video coding (AVC) up to 1080p30. The DX650 can be used in both wired and wireless environments. It includes a 10/100/1000 integrated switch for wired connections. For wireless connections, it has an 802.11a/b/g/ncapable radio built in. Bluetooth support is also built in to this device. The functionality is not simply for headset use, although it works very well with a variety of available models. An additional feature known as Intelligent Proximity for Mobile Voice allows a paired smartphone to make use of the superior audio capabilities of the DX650 for calls to and from that phone. Contacts and call histories can be synchronized into the DX650 as well to provide a more seamless experience. The use of external displays is encouraged with the DX650. It has an HDMI port and a display port for external display connectivity. In addition, it has two standard USB (type A) ports for keyboard/mouse/flash drive, and so on connectivity and one micro-USB port. The DX650 is PoE capable and is a Class 3 device with 802.3af power or class 4 device with 802.3at power. The difference really comes down to what types of devices need to be powered by the USB ports. If higher-power devices are connected, the DX650 must pull more power from the switch. The DX650 comes with the Cisco AnyConnect VPN client embedded; however, it is also compatible with the Cisco mobile and remote-access (a.k.a. collaboration edge) architecture for VPN-less connectivity. Obviously, this access requires a CUCM version capable of supporting that architecture (9.x and later). Otherwise, the DX650 is supported in CUCM 7.1(5) and later. Table 5-11 provides an overview of the features of the DX650. Table 5-11 Cisco DX650 Features F e at ure/ Fun c t i on

For comparison, Figure 5-31 shows the Cisco Jabber for Mac client.

Figure 5-31 Cisco Jabber for Mac

In viewing both Figure 5-30 and Figure 5-31, it becomes evident that these two clients present a common user experience even though they are running on top of two very different platforms. Each has the characteristic aesthetic traits of the OS, but identical in form and function otherwise. The same holds true for Jabber on all supported platforms. Desktop sharing can be initiated from the client as well simply by initiating an IM session. The client can be in either desk phone mode or soft phone mode when the share is initiated. The share can also be used to control the desktop being shared. In cases where the screen share is initiated from a multiparty IM session, the screen share can include up to five participants. No call need be active between the two endpoints. If only an IM session is active, the screen share is initiated via XMPP. If a call is active, the share is initiated via Binary

CCNA Collaboration CIVND 210-065 Official Cert Guide

Floor Control Protocol (BFCP). This is a relatively new addition, however, in Jabber 10.5 and later. Note that that IM-only screen share is using Remote Desktop Protocol (RDP) to accomplish the connection. Therefore, it is available only with Jabber for Windows. Prior to Jabber 10.5, only BFCP was used for desktop share, and no remote control capability was possible. This necessitated the need for the Jabber client to be in soft phone mode and a call to be up between the desktops to initiate the share. This is no longer the case. But, it is useful to understand the history for a number of reasons, potential exam coverage included.

Cisco Jabber for Tablet Cisco Jabber for iPad and Android enable mobile users to make use of Jabber on a mobile platform somewhat larger than the smartphone and more portable than even the smallest laptop computer. Tablets have taken over as the perfect balance of application portability and screen real estate. It is only natural that they become an extension of our work desktop. Using the Jabber client enables the full collaboration experience in a very small footprint. This includes IM, presence, voice, HD video, content sharing, and so on. It will run on iPad, iPad mini, or an Android tablet. Figure 5-32 shows the Cisco Jabber for iPad client.

Figure 5-32 Cisco Jabber for iPad

Figure 5-32 shows the video call layout with picture-in-picture and call controls. During a video call, the camera in use can be switched from forward to rear and back at will. For comparison, and to show a slightly different view of Jabber’s functionality, Figure 5-33 shows the Jabber for Android client running on a tablet. Figure 5-33 shows the Jabber client contacts and IM screen. The Jabber client on both platforms has the same look, feel, and capabilities. The quality of video will, of course, be subject to the wireless network radio, processor and optics capabilities of the tablet. For example, the quality of the experience on a new iPad Air with Retina camera and display will be superior to that on an iPad 3 without Retina capabilities.

Cisco Jabber for Smartphone On the smartphone front, the Jabber client runs on the iPhone and Android platforms. Like the tablet versions, the smartphone versions will support IM, presence, voice, and HD video. Again, the video quality is subject to hardware capabilities.

CHAPTER 6

Configuring Cisco Unified IP Phones and Cisco Jabber This chapter discusses the configuration of the Cisco IP Phone models referenced on the exam blueprint and also discusses Cisco Jabber. Chapter 5, “Cisco IP Phones, Desk Endpoints, and Jabber Overview,” discussed a wider array of the overall Cisco IP Phone portfolio. Cisco IP Phone configuration does not vary by a significant degree from model to model across the IP Phone portfolio. That said, this chapter touches on the line-side protocols in use, the IP Phone boot and registration process, general configuration parameters, and status verification mechanisms available for the phones. In addition, the discussion delves into the configuration of Cisco Jabber. The focus remains primarily on the client configuration options. However, some discussion of server-side parameters is required on a number of fronts, including the Cisco Unified Communications Manager (CUCM) service profiles and Domain Name System (DNS) records necessary for Jabber to discover services and function properly.

Foundation Topics Cisco Collaboration Endpoint Protocol Overview A protocol, generally defined, is merely a set of rules for a given scenario or situation. In the medical field, a protocol is a specific set of steps that must be followed to ensure proper, consistent patient care. In social settings, protocol is known more commonly as etiquette. No matter how you view it, protocol is an agreed upon manner of behavior for a given scenario. In this case, the protocols relevant to this discussion are the rules dealing specifically with the need to provide a means of communication between call control and endpoints. To facilitate said communication, additional protocols are required in the underlying infrastructure. TCP/IP is one of those, certainly. But, this book is not about TCP/IP, specifically. That said, some aspects and underlying components of the larger TCP/IP suite of protocols are relevant. The protocols associated specifically with Cisco collaboration architectures are rather numerous. Those relevant to the discussions within this book, and certainly within this chapter, are not quite so numerous. There are protocols specific to discovery and information relay. There are protocols specific to IP addressing and file transfer. The list includes the following: ■

Cisco Discovery Protocol (CDP)

■

Link Layer Discovery Protocol for Media Endpoint Devices (LLDP-MED)

■

Dynamic Host Control Protocol (DHCP)

■

Trivial File Transfer Protocol (TFTP)

■

Hypertext Transfer Protocol (HTTP)

■

Skinny Client Control Protocol (SCCP)

■

Session Initiation Protocol (SIP)

■ ■

Real-time Transport Protocol (RTP) Secure Real-time Transport Protocol (SRTP)

■

Simple Object Access Protocol (SOAP)

■

Extensible Messaging and Presence Protocol (XMPP)

■

Lightweight Directory Access Protocol (LDAP)

■

Computer Telephony Interface (CTI)

■

Computer Telephony Interface Quick Buffer Encoding (CTIQBE)

■

Cisco Audio Session Tunnel (CAST)

■

Internet Message Access Protocol (IMAP)

Table 6-2 details the protocols of particular relevance to Cisco collaboration endpoints.

Chapter 6: Configuring Cisco Unified IP Phones and Cisco Jabber

On this page, you have numerous options. Only a few of them are actually required. The first of these is the MAC address. All the required fields have an asterisk next to the field names for emphasis. When you complete the device configuration and then click the Save button, a column of button configuration links is added vertically along the left side of the page according to the phone button template selected for the endpoint. Also, at this point, a configuration file for the phone is created and added to the TFTP server so that it can be downloaded once the phone connects. Using these newly provided links, directory number (DN) buttons, intercom buttons, busy lamp field (BLF) buttons, application buttons, and more can be assigned. Figure 6-3 shows a DX650 configuration page with an assigned DN.

6

Figure 6-3 Cisco DX650 Configuration Page

In the figure, you can see the DN along with numerous configurable speed dial (SD) options. The device will register and download its firmware and configuration file once it is connected to the network and has booted completely. One item of note in the new endpoints, 7800/8800, DX series, and so on is that the means by which firmware upgrades occur has been altered. In the past, when a phone registered, it downloaded its firmware immediately, before it was fully registered and usable. Now, firmware is downloaded while the device is in a usable state. The device will boot with its existing firmware, register, and be operational. When a firmware upgrade is needed, the firmware is downloaded in the background, and then the user is prompted to allow the endpoint to reboot to complete the upgrade. This reduces the overall user impact of firmware upgrades/changes. Note that when new phones are added to the portfolio, they have to be added to CUCM. This is done through the installation of a device pack. Device packs can be downloaded from the Cisco Communications Manager Updates page on Cisco.com. Individual phones

136

CCNA Collaboration CIVND 210-065 Official Cert Guide

can be added manually; however, for purposes of maintaining the most up-to-date firmware for all endpoints, the device pack is preferred. Once the device pack is installed, there will be a full-cluster reboot required to complete the installation. So, be sure to schedule a maintenance window. Should it become necessary to manually configure a phone, for some reason, all that is required is power. Whether that power comes from an actual power cord or via Power over Ethernet (PoE) is not overly important at this point. The settings for the endpoint are accessed by various means depending on the endpoint model. For the 7800/8800/9900 series there a button with an icon of a cog, which represents the settings. Figurephones, 6-4 shows theis9971 and its settings button.

Figure 6-4 Cisco 9971 Settings Button

Upon pressing the settings button, a menu of options is shown on the screen. Select Applications > Administrator Settings > Network Setup > Ethernet Setup. On this screen, a number of options exist, including the ability to view the VLAN ID, domain name, or MAC address. In addition, the IPv4/IPv6 settings can be altered here. If the IP address needs to be statically configured, select IPv4 setup and ensure that the DHCP Enabled switch is set to No. (It is set to Yes by default.) At that point, the IP options can be manually entered. If a change is made, click Apply. More typically, there will be a need to specify an alternate TFTP server. Using the arrow keys, scroll down to the Alternate TFTPoption and set it to Yes. Then enter the address of the TFTP servers as needed. Click Apply.

CCNA Collaboration CIVND 210-065 Official Cert Guide

Cisco created “inline power” in 2000 as a response to a growing desire in the IP telephony and wireless access arenas to be able to forego the need for power supplies on phones and access points, respectively. The idea of the phone drawing power from the wall jack to which it is connected is nothing new. At the time, there was no industry standard way of providing said power for IP Phones. When the IEEE ratified the 802.3af specification, Cisco retired the proprietary inline power functionality. The IEEE has further advanced the capabilities with the ratification of 802.3at PoE. PoE is something of a science all on its own. There are a variety of levels of power that a LAN switchsupply. can provide. Usually, level ofpower PoE capabilities thebeswitch is based on its own power In many cases,the a switch’s supply mayon not sufficient to allow for PoE to all ports. Or, it may only be able to provide a certain wattage per port. The wattage requirements for endpoints will certainly depend on the endpoint and its capabilities. Typically, the more feature-rich the endpoint, the more power required to run it. The industry refers to these power differences as the class of the device, ranging from Class 0 to Class 4. With regard to 802.3af, Classes 0–3 were used, and Class 4 was reserved. With 802.3at arriving on the scene, Class 4 has been defined, but only for 802.3at-capable devices. Table 6-3 shows the PoE classes and power specifications. There are two defined entities to keep in mind: power sourcing equipment (PSE) and powered device (PD). The PSE is the LAN switch, and the PD is the endpoint or access point. Table 6-3

Defaultclassification

When the endpoint is connected to the access layer switch, if it is not connected to external power, it attempts to obtain power via PoE. Initially, the switch responds by going into what is called a resistive detection and classification stage. This is a protective mechanism to guard against damaging connected devices. There a resistance of 25 ohms in PoE-compliant devices. Assuming that stage passes, the switch responds by applying power in low power mode with 6.3W to allow the phone to boot. Cisco endpoints use CDP to make a specific request to Cisco switches for the amount of power they require. CDP also informs the endpoint of the voice/video VLAN ID to which it should attach. Optionally, LLDP-MED can be used for similar functionality. With the phone now powered up sufficiently, the boot process continues. The next order of business is the acquisition of IP addressing and TFTP services. This is done via DHCP, assuming that static configuration is not being used. The endpoint broadcasts a DHCPDISCOVER on the VLAN provided by CDP/LLDP-MED. In response, one or more

Chapter 6: Configuring Cisco Unified IP Phones and Cisco Jabber

139

DHCPOFFER messages is sent from the DHCP server to the requesting endpoint via unicast. The information in the DHCPOFFER includes the IP address, subnet mask, default gateway, DNS, and TFTP Option 150 address. With that information in hand, the endpoint can proceed on to the next step, contacting the TFTP server. The TFTP Option 150 address contained in the DHCPOFFER is used to send a TFTP/HTTP GET request to the TFTP server. The request is looking for a specific filename based on the MAC address of the endpoint. The MAC address of the endpoint can be found on the back near the bottom, in most cases. Figure 6-6 shows the location of the MAC address on the back of an 8861 phone.

6

Figure 6-6 Cisco 8861 IP Phone MAC Address Location

Based on the endpoint model, the general layout will vary. At times, it will be in a row across the bottom of the device rather than as shown in the figure. Hopefully, the MAC address will have already been located as part of preconfiguring the phone in CUCM. However, if auto-registration was used, it may not have been manually located. The file being requested at this point from the TFTP server is in the format SEP.cnf.xml. So, if the MAC address were 00C0.1CBE.1EA8, the TFTP/HTTP GET request would be made for the file SEP00C01CBE1EA8.cnf.xml. Once the file is retrieved, it is parsed and loaded. The endpoint will also examine its running firmware version versus the version specified in the configuration file. If so, it continues on with the registration process. If not, it requests the firmware files.

CUCM is required to provide call control as well as licensing and the user database for the IM&P server. In full UC mode, a single IM&P server can support up to 15,000 users. A cluster of three IM&P servers can support up to 45,000 users for full UC. High availability (HA) is also an option in the IM&P server architecture. For IM-only deployments, a single server can support 25,000 users and a cluster, 75,000 users. The HA option is available for this deployment as well. When configuring Jabber in CUCM (for full UC and phone mode), a CSF profile is required. This is the equivalent of an endpoint configuration for a physical endpoint. The device name in CUCM needs to begin with CSF, followed by an arbitrary identifier, usually a user ID. For example, CSFJDOE would be the device name for John Doe’s Jabber device in CUCM. Jabber users are identified by a Jabber ID (JID). It consists of a Jabber username and a domain name in much the same way an e-mail address or a URI is formatted. Users can be created on CUCM or synchronized from an Active Directory (AD) or LDAP server. User authentication is done by CUCM for locally created users and proxied to the AD/LDAP server for synchronized users. Jabber makes use of SOAP over HTTPS upon its launch in communicating to the IM&P server to retrieve its configuration. Jabber makes contact with CUCM via HTTP and HTTPS to retrieve a list of devices associated to the user who is logging in. XMPP is used in communication with the IM&P Server for presence status and IM functionality. LDAP is used for directory searches when looking for contacts with whom to communicate. From a telephony perspective, Jabber is a soft phone registering to CUCM. As such, it acts very much like the endpoints discussed earlier in this chapter. It makes contact with the TFTP server, pulls its configuration file, and then registers to CUCM as a SIP endpoint. It can use both RTP and SRTP for media in both audio and video communications as configured by the CUCM administrator. Jabber makes use of a Cisco CallManager Cisco IP Phone (CCMCIP) service profile in retrieve settings and information about devices associated with a particular user. This list of devices is used in populating the Desk Phone Control field in the Jabber client. In communicating with Unity Connection, the Jabber client uses an IMAP connection to retrieve and manage the list of voice messages for the logged-in user and to retrieve and manage the messages themselves. Note While divided into component services in Figure 6-8, it is highly probable that

the TFTP server, CTI Manager service, and CCMCIP service will all be running on CUCM. Certainly, they will be running on a CUCM node, if not the CUCM Publisher itself. They do not have to be on individual node instances.

CCNA Collaboration CIVND 210-065 Official Cert Guide

Figure 6-10 Cisco Jabber for Windows Login Prompt

Jabber will use the domain portion of the JID provided to resolve the services via DNS SRV records. Optionally, an administrator can provide the domain name either via modifications to the Windows Installer or through a URL configured in the local jabber-config.xml file. In this case, the user will not need to provide domain information. Regardless of the method used, it then caches the domain information for future logins. Jabber sends HTTP and DNS requests simultaneously in search of its services. This allows the discovery of on-premises and cloud-based services. The HTTP requests are sent to the Cisco WebEx Cloud service. The DNS requests are sent to the configured, either statically or dynamically, DNS servers for the client. When configuring the DNS SRV records, the fully qualified domain name (FQDN) of the respective entities to which the records refer should always be used. That, of course, also adds a requirement that DNS A records be created for each CUCM node, the IM&P server, and the VCE-E or Expressway-E as applicable. Table 6-5 shows the DNS SRV records used by Jabber for service discovery. Table 6-5

Figure 6-11 Cisco Jabber for Windows Manual Configuration

If configured manually, the client may not have the flexibility to roam into and out of the network as the addresses configured inside the network may be different than those required outside of the network. For this reason, the automatic configuration and service discovery using DNS SRV records is the preferred way to deploy. When the client makes contact with the IM&P server, the determination as to whether the user is permitted to use Jabber is made. This validation is done by CUCM. A check box on the user page allows the use of IM and Presence. Figure 6-12 shows the End User Configuration page.

Chapter 6: Configuring Cisco Unified IP Phones and Cisco Jabber

If the user is logging in using soft phone mode, a TFTP request is made for the configuration file for the associated Jabber client device provisioned in CUCM. The formatting of the device name is dependent on the type of client logging in. Each of the options, however, should include the prefix and the username. For example, [email protected] would have an associated Jabber for Windows device named CSFUSER1 in CUCM. The Jabber client then issues a SIP REGISTER message to CUCM, which then responds with SIP 200 OK. The Jabber client can now make calls. In addition to registering with CUCM, the Jabber client will log in to the other configured services in the UC Service Profile (for example Unity Connection). When it contacts Unity Connection, it pulls a list of messages and the read/ unread state of each. If the Jabber client is logging in using desk phone mode, it initiates a CTI connection to the CUCM CTI Manager for desk phone control. It can then control the on-hook/off-hook state of the phone and its available resources for audio/video.

Tuning The Jabber client can be tuned for audio and video operating levels at both the operating system (OS) level and within the Jabber client. A camera must be connected to the desktop machine for the Jabber client to use local video. In like fashion, there must be an existing microphone and speakers for audio to function properly in soft phone mode. Figure 6-13 shows the tuning options in the Jabber for Mac preferences configuration.

There is a specific menu within the Administrator Settings for Status information. The submenus provide a significant amount of information about the phone, its connectivity, both wired and wireless. This discussion covers only the wired information. It also includes information about call quality. The options here include the following: ■

Status Messages

■

Ethernet Statistics

■

Wireless Statistics

■

The Status Messages screen contains event log information such as TFTP file download verification, TFTP file timeouts, trust list updates, vi rtual private network (VPN) connection information, and so on. If the phone is not registering for some reason, clues to the reasons why that is the ca se may often be found h ere. Figure 6-15 shows the status screen of the 9971. 6

Network connectivity options on the 9971 include both wired and wireless options. When connected to the wired interface, the Ethernet Statistics screen shows receive and transmit frames, broadcasts, connection time, and speed/duplex information. The Wireless Statistics screen provides much of the same information, though it adds multicast and QoS-related information. Figure 6-16 shows the 9971 Ethernet Statistics screen.

CHAPTER 7

Cisco TelePresence Endpoint Characteristics Much of the growth Cisco has experienced throughout the years has been attributed to key acquisitions. In doing so, Cisco has developed a vast range of product offerings for customers to choose from. In addition, Cisco differentiates between Unified Communications (UC) endpoints and TelePresence endpoints. And if that is not confusing enough, there are significant differences between Cisco TelePresence endpoints as well. This chapter discusses TelePresence endpoints within Cisco’s product line. This chapter notes key differences between the software bases for each product grouping, identifies what call control servers can be used for each product grouping, and discusses relative characteristics for each endpoint.

parameters necessary for provisioning to work. In addition, TMS creates two databases: TMS Agent and SQL. This is a second sequence of SQL dedicated exclusively to TMSPE. The first step in configuring provisioning is to establish replication between TMS and the VCS. To enable replication, the VCS must have the device provisioning option key installed. This option key enables two databases on the VCS, TMS Agent, and Open DS. To establish replication, on TMS go the System menu and the Navigator submenu. Click the VCS, and then click the Provisioning tab. Configure the settings displayed on this page. A visual confirmation will indicate replication is established. Figure 7-3 illustrates the provisioning configuration settings on TMS, along with the visual confirmation indicating replication has been established.

Figure 7-3 Replication Configurations on TMS to the VCS

Information that is replicated between the VCS and TMS include user account information, phonebooks, and the availability of provisioning licenses, which exist on TMS. This information is stored on the Open DS and SQL databases enabled with provisioning. Once replication has been established, the next step is to configure the provisioning database on TMS. This can be found by navigating to the System menu and the Provisioning submenu. The Provisioning submenu has three options: Users, FindMe, and Devices. The Users option is where all the configurations for Jabber Video for TelePresence need to be configured. The elements that need configured here include groups, users, user settings, configuration templates, and schemas. Groups are used to segregate users based on varying privilege levels that will be assigned to them using templates. If all users will share the same

Chapter 7: Cisco TelePresence Endpoint Characteristics

171

privileges, no additional groups need to be configured. User settings are the URI schemes that will be used for dialing and identifying Jabber Video for TelePresence clients. These URI patterns are template based so that they can be applied to all users within a group. Schemas are sets of configuration options based on the system type and version being used. For each schema used, a template must be configured. Templates are the configurations settings that will be applied to a group of users. Each schema must have at least one template associated with it, but schemas can support multiple templates as well. Users can be configured manually or integrated through a Lightweight Directory Access Protocol (LDAP) server, like Microsoft Active Directory (AD). To create groups, select the root group, and then click the Add Group button at the top of the left column. When the pop-up window appears, enter the group name and click Save. Once a group has been created, users can be added to that group. To add a manual user, click the Add User button at the top of the left column. The top three fields must be configured at a minimum. They are Display Name, User Name, and Password. Click Save when finished. Figure 7-4 shows the Add Group and Add User buttons, along with the manual user configuration pop-up window.

Figure 7-4 Adding Groups and Users to TMS

To integrate LDAP users, click the Configure button under the User Import menu in the right column. Select the type from the drop-down list of choices. They are Active Directory (AD), Active Directory with Kerberos (Secure AD), and Lightweight Directory Access Protocol (LDAP). Fill in the configuration fields presented on the pop-up window and click Save. Once complete, synchronization with the LDAP server can be initiated by clicking the Sync Now button. Figure 7-5 shows the configuration fields needed for AD integration.

Now that groups and users have been added to the provisioning directory, user settings can be configured. In the right column, click Edit under User Settings. At a minimum, the video address pattern and device address pattern must be configured. The video address pattern is the address that will be displayed on a destination endpoint when in a call. The device address pattern is the address that will be used to dial provisioned devices. Typically, these patterns are configured the same. Click OK when finished. Figure 7-6 shows how these user settings are configured.

Figure 7-6 User Settings Configuration

Now you can add schemas. At the bottom of the left column, click the Configuration Templates menu. Click the Add Schema button at the top of the left column, browse to where the schema is located on your computer, and then click OK. Figure 7-7 shows how to browse for schemas.

173

Figure 7-7 How to Browse for Schemas

After all schemas have been uploaded to TMS, templates can be created based on these schemas. Select a schema, and then click the Add Template button at the top of the left column. Configure a name for the template and click OK. Select the template that was just created in the right column, and click Edit Configurations below the Configurations section. Configure all the configuration settings needed and click Save. Many setting options within a template can be configured. Cisco recommends three settings be configured at a minimum. Those three settings are the SIP Server Address, Presence Server URI, and the Phone Book Server URI. Figure 7-8 shows how to configure templates.

Summary Cisco has many endpoint solutions available that span three main software-based platforms. They are CTS software based, Android software based, and TC software based. These endpoints have a variety of different features, use two different communication protocols to communicate (SIP and H.323), and register to two different call control servers (Cisco Unified CM and Cisco VCS). Some of the key topics discussed include how TIP works using immersive telepresence room solutions with multiplexing technology for RTP and RTPC protocols. Nonimmersive CTS endpoints include the CTS 500, CTS 1100, and the TX1300 endpoints. Immersive endpoints include the TX9000 series and the new IX5000

series. DX series endpoints include the DX650, DX70, and DX80. The TC portfolio is the most expansive of the three previously mentioned software-based product lines. SX endpoints include the SX10, SX20, and the SX80. Other integrator systems include the C40, C60, and C90. Personal systems include the EX60 and the EX90. Comparisons were made between the MX200 and MX200G2, in addition to between the MX300 and MX300G2. Other MX meeting room solutions include the MX700 and the MX800. Many different peripheral devices can be used in conjunction with these TC endpoints (namely, the new and improved cameras called Precision60 cameras, which work with the SpeakerTrack dual camera option). Other great and innovative products are the Touch 8 and Touch 10 controller pads. Intelligent Proximity for Content Sharing is another great example of the leading ingenuity Cisco brings to collaboration solutions. Finally, there is the Cisco Jabber Video for TelePresence soft client that brings mobility together with Cisco’s premium HD video solutions.

CHAPTER 8

Configuring Cisco TelePresence CTS Software-Based Endpoints The endpoint platform Cisco came out with that they are the proudest of is Cisco TelePresence System (CTS) software-based endpoints. Originally, the Cisco Unified Communications (UC) platform dealt primarily with Voice over IP (VoIP). The way in which the CTS endpoint was developed allows the TelePresence video endpoint to register and setup calls in the same fashion. This chapter looks more closely at the similarities of the registration process the CTS endpoint uses to that of other UC products. Further discussion includes a beginning-to-end process demonstrating how to configure the CTS endpoint, calibrate it to the room environment, and set up and support user accounts.

Foundation Topics Cisco TelePresence CTS Software-Based Endpoint Overview To better understand the Cisco TelePresence CTS software-based endpoints, an understanding of how the endpoints communicate within a network is needed. CTS software-based endpoints only register to the Cisco Unified CM; therefore, the process of registering a CTS is no different UCendpoint. endpointsThere communicate a network. The focusendpoint of this chapter is on thefrom CTS how 500-32 are somewithin differences to setting up other CTS software-based endpoints, primarily because they all use a camera cluster with three cameras. The immersive TelePresence solutions also use three or more monitors. Because the CTS 500-32 endpoints come with only a single camera and monitor, they can leverage a First-Time Setup Wizard as well. This Setup Wizard is available only on the CTS 500-32 endpoints, but more on that later. The first object that needs to be identified when setting up CTS 500-32 endpoints is the control device used to interface with them. Cisco makes two options available to the customer. The first is a Cisco 7970G or 7975G VoIP phone. Alternatively, the Cisco Touch 12 can be used. The following steps outline the process a CTS 500-32 endpoint goes through to register to the Cisco Unified CM: 1.

A Cisco CTS 500-32 endpoint receives power from a power cube. When a VoIP phone is used, it receives PoE from the CTS 500-32 endpoint, but both endpoints send separate communications out across the network.

2.

The first message they send out is the Cisco Discovery Protocol (CDP) to the switch. This CDP communication is used to obtain the voice VLAN information.

3.

Once VLAN discovery is complete, the two endpoints will a Dynamic Host Control Protocol (DHCP) Discovery message to the DHCP server. Typically the DHCP server is a router, but the Cisco Unified CM can also fulfill this role. A limitation in using the Cisco Unified CM is that it only allows support for 1000 devices. However, in either case, an option is made available for the TFTP server address to be discovered at the same time. This option is called Option 150 . Once the DHCP server receives the DHCP Discovery, it responds with a DHCP Offer. The DHCP offer includes an IP address, subnet mask, default gateway address, TFTP server address (with use of Option 150), and possibly one or more Domain Name System (DNS) addresses. The endpoints respond to the DHCP Offer with a DHCP Request for the specific information sent in the DHCP Offer. The DHCP server then sends a DHCP Acknowledgment authorizing the use of the DHCP information exchanged and end the DHCP session.

4.

Now that both endpoints have appropriate IP address information and the TFTP server address, they can send a TFTP Get message to the TFTP server. This message is typically sent over HTTP when using current endpoints, although TFTP signaling could be used as well. The communication the endpoints sent to the TFTP server contains their MAC addresses because that is what the Cisco Unified CM uses to identify the endpoint. The first element the endpoint tries to download is a certificate trust

CCNA Collaboration CIVND 210-065 Official Cert Guide

The CTS 500-32 endpoint allows users to interact with it using the CLI as well. Before using the CLI, it is important to understand that there is no Telnet support on this device, nor is there a serial or console interface. Therefore, only Secure Shell (SSH) can be used. To use SSH, you need to use an emulator, like PuTTY, to begin the session. Enter the IP address of the endpoint and click Open. When prompted, enter the username and password. When you see the admin: prompt, you have successfully logged in. The command structure is similar to the CLI of the Cisco Unified CM, because it is built from the same Red Hat software kernel. The ? can be used to list commands that are less familiar. Some of the base-level commands are utils, show, call, and set. Whereas calls could not be initiated from the web interface, they can be initiated from the CLI. The third way users can interact with the CTS 500-32 endpoint is by using the Cisco Touch 12 control pad. Menu options only display on the Cisco Touch 12 after the endpoint has registered and the Touch 12 has received its system load file from the endpoint. The user options are limited on the Touch 12 as compared to the web interface and the CLI. Your average user will only need to use the control pad for basic calling functions on the CTS 500-32 endpoint. Therefore, the Touch 12 can be used to place calls, end calls, and share content. If OBTP is scheduled with the CTS 500-32 endpoint, a button will appear on the control pad to start the meeting. Users can also view call statistic information using this device.

Configuring CTS Software-Based Endpoints You must consider several factors when setting up the CTS 500-32 endpoint for the first time. Such factors include how the endpoint obtains IP information and how it communicates with the TFTP server. In the event that the system requires a factory reset, you must consider what options exist and the impact this operation has on the endpoint. Like any endpoint that registers to the Cisco Unified CM, a phone must be configured on the Cisco Unified CM before registering the endpoint. Outside of SSH access via the CLI, there is no real security established on the endpoint itself. These security settings are configured on the Cisco Unified CM when the phone configuration file is created. This section focuses on registering the phone. Securing the endpoint is discussed in the section “CTS SoftwareBased Endpoint User Accounts.” By default, the CTS 500-32 endpoint uses DHCP to obtain IP address information. Should the endpoint need to be rebooted at any time, the IP information obtained during the DHCP process will be cached and reused after the reboot process is complete. When the endpoint first boots, the user will first see the Touch 12 and the monitor power on. The monitor will display the Cisco name and logo for about 60 seconds and then return to sleep mode. Meanwhile, the control pad displays circles in the lower-left corner of the screen numbered 1 through 7. These are POST tests of sorts that the endpoint uses throughout the boot and registration process. When the Touch 12 gets to the number 4 circle, the monitor wakes up again and displays its own circles numbered 1 through 6. In addition, a box on the right side of the monitor lists MAC, IP, VLAN, 802.1X, and CTS S/W. The MAC address settings and CTS S/W settings will display immediately, and the 802.1X will display Not Required. However, the IP and VLAN options will first appear blank. When the CDP and DHCP processes are complete, the IP and VLAN information will display. Figure 8-4 shows what the monitor might look like during a CTS 500-32 system startup.

Figure 8-7 First-Time Setup Wizard

As you can see in Figure 8-7, the settings that this wizard will calibrate include the touch verification, display verification, eye height setup, camera setup, audio verification, and VGA verification. To start the First-Time Setup Wizard, click the Start button. The first setting that you need to calibrate is the Touch 12. Several buttons will appear on the touch display that you will need to “touch” to calibrate this device. Click the Next button when calibration of the Touch 12 is complete. The next screen is Display Verification. There will be an image on the display that should match the image on the web interface. If they match, click Next to calibrate the eye height setup. A red square will display on the monitor. Press the button located on the back of the pedestal the CTS 500-32 endpoint is mounted on, and elevate or lower the monitor so that a person’s face would center in the red square when seated in front of the camera. Once the height is set correctly, the camera can be calibrated. This the .most difficult part of the process.on Locate cardboard cutout clickisNext The cardboard cutout hascalibration a pattern printed it thatthe looks like a QR codeand and can be folded into a triangle. The monitor displays the same red square from the previous step. Align the cardboard cutout so that the pattern fills the inside of the red square. It is important that the cardboard cutout be very still. It is best to stack boxes or something that it can be placed on so that there is almost no movement at all. When ready, click the Start button from the web interface, and the camera will take a picture of the image on the cardboard cutout. That picture will display on the monitor beside an image that is should match to. If the picture is blurry and out of focus, you can manually adjust the camera to focus the picture. Pull the cover off the camera and adjust the zoom and focus of the lens. Click the Try Again button in the web interface to take a picture again. The camera can also be manually adjusted for pan, tilt, and horizon. There are tiny screws on the bottom of the camera that can be used to adjust these settings. When you are satisfied with the camera adjustments and the image quality, click the Next button. Audio verification test the built-in microphone and speakers. A meter will appear on the web interface. Speak in a normal tone and watch the needle on the meter move. Then speak very softly and verify that the microphone can still pick up your voice. Speak louder than normal to ensure the microphone can

handle louder outbursts. For the speaker calibration, the endpoint will emit the Cisco tune over the speakers. Adjust the volume so that the music can be heard at a comfortable volume. The last calibration test is the Video Graphics Array (VGA) connection. Using a VGA cable, connect a laptop computer to the endpoint. Click the Start Presentation button that is made available on the Touch 12. If your computer screen is displayed on the monitor, this step is compete. If not, you may want to check all your connections to ensure that the cables are seated properly. Clicking the Finish button circles you back to the welcome and introduction page shown in Figure 8-7. If you do not want to run the wizard, or if you did run the wizard and you are finished, you can click the CTS Admin UI button. This redirects you to the Web Portal login page for the CTS 500-32 endpoint. If you opted not to run the First-Time Setup Wizard, or you want to recalibrate one of the settings, a tool is provided to perform these tasks from the web interface. After the endpoint has registered, log in to the web interface of the endpoint. In the left menu column under the Troubleshooting section, click the Hardware Setup option. The display field right of the menus will show all the above-mentioned calibration options. Click the option you want to calibrate, and then click the Start button. They can all be calibrated in the same manner as mentioned earlier. Whether the endpoint was set up for the first time or a factory reset was performed on the endpoint, the fact ory image w ill be the boot image the CT S 500-32 endpoint will use each time. An updated image file can be loaded to the endpoint, bu t the factory image will sti ll be used unless the boot slot is changed. To upgrade the end point, a newer version software must be uploaded to the Cisco Unified CM, and the phone load name of the version you want to use must be specified on the phone settings withi n the Cisco Unified CM. Figure 8 -8 illustr ates the field that needs configured on the Cisco Unified CM to specify a phone load name.

Figure 8-10 Password Recovery from the CLI

Summary For engineers who are proficient with working in a Unified Communications environment, the CTS 500-32 endpoint should feel relatively familiar. It functions much like a VoIP phone in as far as how it registers to the Cisco Unified CM. The control device used to place and disconnect calls can even be a VoIP phone, although only the 7970 and 7975 IP Phones are supported. Ideally, the Cisco Touch 12 control pad should be used with these endpoints. Either the IP Phone or the Touch 12 can be used to interface with the endpoint, along with the web interface or the CLI. The endpoint will use DHCP by default, but if there is an issue preventing the endpoint from receiving IP information, it can use the default IP address of 192.168.100.2. This address can be used to change the IP settings to static and assign the necessary addresses. The endpoint will also try to obtain the TFTP server address using Option150. If the TFTP server address is not obtained, this setting can be configured manually on the endpoint as well. Should the endpoint need reset, two options are available for issuing the factory reset. Also, the endpoint can be calibrated using either the First-Time Setup Wizard or the web interface. The two user accounts on the CTS 500-32 endpoint, the admin user and the helpdesk user, can be secured through the Cisco Unified CM. Should the password be lost or forgotten, there is also a recovery component built in to the endpoint to reset the password to its factory setting of Cisco.

CHAPTER 9

Configuring Cisco DX Series Endpoints What does an end user look for in a desktop video endpoint? With today’s standards the first and foremost component is the ability to place high-definition (HD)-quality video and stereo-quality audio calls. Ideally, this epitomized endpoint would serve a purpose beyond video collaboration calling, such as act as a dual monitor for a computer while not in a call. Contacts should be easy to add and access for quickly calling common contacts. These, along with many other features, are considerations Cisco used to design the DX series endpoints. Smartphones are dominating the digital world, allowing users to perform tasks that surpass simply placing a phone call. By giving the DX series endpoints an Android-based operating system (OS), Cisco has been providing this same functionality within these endpoints, from downloading and using apps, to accessing the Internet. This chapter discusses some of the different capabilities and protocols that define the DX series. You will also learn how to use this unique user interface. So that you can register a DX to a call control server so that calls can be sent and received, this chapter also explains explanation how to configure the DX series endpoint and the Cisco Unified Communications Manager (CM).

With an endpoint this feature rich, many organizations may understandably have a concern that their employees will abuse these functions and download games to their phones, or leverage it in some other nonproductive fashion. The world has suffered enough from Candy Crush. As Benjamin Franklin said, “An ounce of prevention is worth a pound of cure.” Cisco has taken preventive steps to allow corporations to customize what end users are allowed to access on their Cisco DX series endpoint. Cisco offers security at multiple levels of the network. Security Enhanced (SE) Android provides more protection by isolating applications to keep sensitive data safer. And your IT admin has the option to limit device capabilities. Some of the functions on the Cisco DX series endpoints that can be administratively disabled include Google Play, Wi-Fi, Bluetooth, installation of apps from unknown sources, and USB ports. On a Cisco DX650, you can enable phone-only mode to provide the following limitations: ■

The user is limited to the home screen, phone application, Contacts application, and Settings application.

■

The user cannot add shortcuts or widgets to the home screen.

■

Any contacts that are saved to the Contacts application in phone-only mode are stored locally and will not sync to any server.

■

USB storage devices and SD cards are not supported.

■

Any previously configured account data is hidden from the user when the phone enters phone-only mode.

■

The phone reboots when you switch from standard profile to phone-only mode, or from phone-only mode to standard profile.

There are two operating modes for the DX series endpoints: simple and enhanced. Simple mode offers the following features and limitations: ■ ■

User cannot modify wallpaper (supports admin-assigned wallpaper).

■

User can not move/add shortcuts or widgets, launch applications, or long click. No Android applications are allowed, and Google Search is removed.

■

External USB storage is disabled.

■

User can create and store local contacts.

■

Bluetooth contacts and history sharing is also allowed.

■

Enhanced mode enables user access to all collaboration goodies, including Jabber, WebEx, Exchange, and Google Play.

These are common reasons an endpoint will not register.

Summary The Cisco DX series endpoints are next-generation endpoints that deliver powerful, highquality communications and collaboration for a variety of office environments. The Cisco DX series endpoints provide native support for HD video up to 1080p30 using the video codec H.264. They also support the annex codec H.264 AVC for HD video at even less bandwidth. Many features are supported on these endpoints, such as access to cloud services, IM, and presence with Cisco Jabber and support for EM. The three main capabilities of DX series endpoints are registration to the Cisco Unified CM for audio and video call admission and control, an Android-based applications feature that increases productivity in the workplace, and an administrative function that allows complete control over what features the Cisco DX series are available for users to access. In addition, the Cisco DXonseries endpoints have aendpoints built-in function that allows Cisco Intelligent Proximity for Mobile Voice to be leveraged through Bluetooth technology, so contacts and call history can be shared between your smartphone and the endpoint, and mobile phone calls can be picked up, mid-call, from the Cisco DX series endpoints. Cisco DX series endpoints register exclusively with the Cisco Unified CM. The process for registering these endpoints is the same as other devices within the Cisco unified communications and collaboration portfolio. This simplifies the process by not having extra steps in the process, and it simplifies the troubleshooting process should problems be encountered. Certain settings must be configured on the Cisco Unified CM before the endpoint can register. Best practice is to configure the Cisco Unified CM first, and then set up Option 150 and let DHCP deliver the TFTP addresses to the Cisco DX series endpoints. This “behind the curtain” approach makes setup of the Cisco DX series endpoints as simple as cabling up and powering on the endpoint for the endpoint to register with the Cisco Unified CM.

CHAPTER 10

Configuring Cisco TelePresence TC Software-Based Endpoints When TANDBERG acquired a company called Codian, the engineers at Codian were developing an endpoint. After the acquisition, TANDBERG finished the development project and named the software for the endpoints TC, for TANDBERG Codian. All TC software-based endpoints can be configured the same way, and the interfaces are the same, making it easy for an administrator to deploy different models of TC software-based endpoints. This chapter discusses a beginning-to-end process that shows how to configure the TC endpoint for both a Cisco Unified Communications Manager (CM) and a Cisco Video Communications Server (VCS). The discussion also covers how to calibrate an endpoint to the room environment and how to set up and support user accounts and control basic calling features.

Foundation Topics Cisco TelePresence TC Software-Based Endpoint Overview Cisco TC software-based endpoints can register with a Cisco Unified CM using Session Initiation Protocol (SIP), or they can register with the Cisco VCS using SIP or H.323. To better understand the Cisco TC software-based endpoints, an understanding of how the endpoints call control servers needed. theservers Cisco Unified CM or thecommunicate VCS is being with used both for communication usingisSIP, both Whether call control are acting as a SIP server. The SIP server is often referred to as the SIP proxy or the SIP registrar, although these are actually functions of the SIP server. If the endpoint is communicating to the VCS using H.323, the VCS is acting as an H.323 gatekeeper. These terms are important for later discussions.

Configuring a TC Endpoint to Register with a Cisco Unified CM If an administrator is configuring a TC endpoint to register with a Cisco Unified CM, the fist step is to cable up the endpoint and turn it on. How the endpoint is cabled up will depend on the type of endpoint being used. You may want to review Chapter 7, “Cisco TelePresence Endpoint Characteristics,” where these different options are discussed in length. After the endpoint has booted and loaded its locally stored image file, it can be configured to register with the Cisco Unified CM. TC endpoints can use Cisco Discovery Protocol (CDP) for VLAN discovery, but this option is disabled on the endpoint by default. When the unit is configured to register with the Cisco Unified CM VLAN, discovery is enabled. If an administrator wants to use VLAN discovery in a VCS environment, this setting must be enabled manually. When VLAN discovery is complete, the endpoint sends a DHCP Discovery message to server.address Similar to environment, 150 can be made forthe theDHCP TFTP server to abeUC discovered at theOption same time; however, theavailable DHCP RequestTFTPServerAddress setting on a TC endpoint must be enabled for TFTP discovery to work. For the time it takes to turn this setting on, the External Manager settings could be configured, so it may prove most prudent just to configure the External Manager settings manually. Now that the endpoint has appropriate IP address information and the TFTP server address, it can send a TFTP Get message to the TFTP server. The communication the endpoints send to the TFTP server contains their MAC addresses because that is what the Cisco Unified CM uses to identify the endpoint. Similar to UC environments, the first element the endpoint tries to download is a certificate trust list (CTL) file. The CTL file contains a set of certificates and is used only when Cisco Unified CM cluster security has been enabled. Next, the endpoints try to download their own configuration files. After the configuration file has been downloaded, the endpoints verify that they are running the requested load or firmware version. TC endpoints will not try to download upgrade firmware files. Although this is Cisco’s intent for future versions, as of 10.x on the Cisco Unified CM the TC endpoint only validates if the version it is running is a supported version.

224

CCNA Collaboration CIVND 210-065 Official Cert Guide

source endpoint dials the destination alias. When the VCS receives the ARQ message, it responds with a Request In Process (RIP) message. This is when the VCS reviews all CAC settings that have been configured and tries to locate the destination alias. If there is some CAC in place that prohibits the call from continuing, the VCS sends an Admission Reject (ARJ) to the source endpoint, and the call attempt ends. If there is no CAC in place that prohibits the call from continuing, the VCS sends an Admission Confirm (ACF) to the source endpoint. This ACF contains the destination endpoint’s IP address. Using that IP, the source endpoint sends an H.225 Call Setup message. This message is sent using the Q.931 protocol from the ITU H.320 umbrella standard for circuit-switched communication. (This was a carryover protocol when the ITU developed the H.323 umbrella standard for packetswitched communication.) When the destination endpoint receives the Call Setup message, it sends the VCS its own ARQ message requesting permission to answer the call. The VCS responds with a RIP message, then an ACF. (Because the two endpoints in this scenario are registered to the same VCS, and there was no CAC prohibiting the call during the first ARQ message, there will be no prohibitions during this second ARQ. If the destination endpoint were registered to a different gatekeeper, there could be cause for CAC to prohibit the destination endpoint from answering the incoming call.) When the ACF is received, the destination endpoint sends two messages to the source endpoint. The first message sent is an H.225 Alerting message using the same Q.931 protocol mentioned before. This Alerting message tells the destination endpoint to ring and sends a ring-back tone to the source endpoint. When the user of the destination endpoint answers the call, an H.225 Connect message is sent using the Q.931 protocol. Most TCP communication uses a three-way handshake (SYN, ACK, SYN/ACK) to establish communication before important packets are sent. In an H.323 call, the call setup process establishes that same open line of communication needed before critical capabilities and UDP port allocations are sent between the two endpoints. The standard used to send this information is H.245. Because this information is sent over TCP, acknowledgments are also sent to confirm receipt of the information being exchanged. The first sets of packets exchanged between the two endpoints are the capabilities exchange. This identifies what audio and video codecs each endpoint supports, in addition to any other capabilities that exist, like far-end camera control (FECC) or content sharing. Next is the master/responder negotiation. (The ITU labels this communication as master/slave negotiation, but it has become common to refer to it as responder instead of slave.) A master must be decided between the two endpoints, and the master will decide what codec is to be used for each capability and what UDP ports each endpoint will use to transmit the packets over. Once the master is decided, that endpoint sends the codec selection and port allocation for itself and the destination endpoint to the destination endpoint. When all the port are open, twoway communication can take place. Figure 10-4 illustrates the H.323 call setup process.

Using the Onscreen Display with the Remote Control The remote control used with all TC endpoints, except for the SX10, is the TRC5 remote. Using this, remote administrators and users can perform most all the functions they need from configuring endpoints to placing calls. However, the SX10 uses a TRC6 remote, which can only be used by users to place calls. All other configuration settings must be done on the SX10 endpoints from either the web interface or the CLI. Note The SX10 does have a Setup Wizard that can be used to provision the

endpoint during the first time it is booted. Device settings must be provisioned from the TFTP server for Cisco Unified CM registration or from TMS (TelePresence Management Suite) for VCS registration.

Figure 10-5 illustrates the button layout of the TRC5 remote control.

Figure 10-5 TRC5 Remote Control

As Figure 10-5 illustrates, five soft keys are located at the top of the remote control. These keys correspond with soft key options that display across the bottom of the display. Different options are made available depending of what the endpoint is doing. For example, if a user is in a call, there is a soft key option for FECC. If an administrator is configuring a

Chapter 10: Configuring Cisco TelePresence TC Software-Based Endpoints

227

setting on the endpoint, there is a soft key option to toggle between numbers and letters. Some soft key options are programmable as well. Below the soft keys in the center of the remote are arrow keys with a checkmark button in the center of them. These arrow keys can be used to navigate menus and to pan and tilt the camera, whether near-end or far-end camera control is being used. The checkmark button is like an Enter key used to make selections. The Zoom button for camera control is located to the right of the arrow keys, and the Volume button is located to the left. Just above the arrow keys are two buttons. The left one is for muting the microphone, and the right one is for sharing content if a device, like a computer, is connected to the endpoint. Below the arrow buttons are three more button options. The left button bring up the phonebooks on the endpoint. The center button is a home button. This displays the main menu options no matter where you have navigated within the menus, or even if there are no menus displayed. The right button is used to bring up the self-view of the camera connected to the endpoint. It can also be used to change the layout if the multisite option is being used. Above the number keypad is the Call Answer and Call Disconnect button. Between them is a C button. This is a Clear, or Backspace, button. It also takes you to the previous menu set when navigating menus using the remote control. Pressing the Home button or the Checkmark button will bring up the first level of menus. Any menu option that has a black arrow beside it means that selecting it will offer another level of menu options. From the main level menus, navigating to Settings > Administrator Settings > Advanced Configuration will take administrators to the menus used to configure and calibrate an endpoint. Figure 10-6 illustrates how these menus will appear.

Using the Web Interface via HTTP or HTTPS The web interface of TC software-based endpoints is a great way to perform more advance functions on the endpoint for administrators who are not familiar with the CLI. The browsers that can be used are mostly all encompassing. Internet Explorer is the most problematic. Firefox and Chrome seem to work the best. Distinguished from the OSD, the main menus of the web interface are horizontally listed across the top of the page. Scrolling over a menu will display the submenu options available. The main configuration and calibration menus can be access by navigating to Configuration > System Configuration. These menu options are exactly the should same asappear they are using TC7.x. the OSD. Figure 10-7 illustrates how the weblisted interface menus as listed of Version

Figure 10-7 Web Interface of a TC7.x Endpoint

Using the Command-Line Interface via Telnet or SSH For administrators who are already familiar with the menus on TC software-based endpoints, the CLI is a great option for interfacing with them. The CLI can be accessed using either Telnet, SSH, or the RS232 serial port available on most TC software-based endpoints. If the serial interface is used, it is important to note that the bit rate is preset on the endpoint at 38400. This setting can be changed, but it is not recommended. There are more options that an administrator can use with the CLI than any other way someone might interface with these endpoints. TC endpoints are built on a Linux platform, and the commands are relatively easy to use. The Help command or the ? command will list all available commands or subcommands, guiding administrators to the exact code line needed. There are three main commands used on TC endpoints:xCommand, xConfiguration, and xStatus. If an administrator wants to tell the endpoint to do something, like place a call or reboot, the xCommand

Chapter 10: Configuring Cisco TelePresence TC Software-Based Endpoints

229

code lines are used. If an administrator wants to verify the status of a call, check network settings, or view the registration status for H.323/SIP, or some other status, the xStatus code line is used. If an administrator wants to configure a setting on the endpoint, the xConfiguration code lines are used. For example, if an administrator wants to identify a system name for an endpoint, the command used isxConfiguration SystemUnit Name: . The code used with xConfiguration maps exactly to the menu structure of the web interface and the OSD. Figure 10-8 lists the commands under xConfiguration using the CLI.

Figure 10-8 xConfiguration Commands Using CLI

Using the Cisco Touch 8 or Touch 10 The forth way users can interact with TC software-based endpoints is by using the Cisco Touch control pad. As mentioned in Chapter 7, the Cisco Touch 10 is used only with MX200G2, MX300G2, MX700, and MX800 endpoints. The EX60 and EX90 come with a Touch 8. The TRC5 remote can be used with these endpoints, but they default using the Touch 8. Also, the Touch 8 used with the EX series endpoints can only be used with those endpoints. However, another Touch 8 option is available for all other TC software-based endpoints except for the SX10. Touch control pads are intended as an easier option for users to interact with TC endpoints. Users can use the Touch control pad to launch calls, end calls, mute microphones, view and select participants from directories, share content, and view statistic information about a call. However, most administrative options are not included with the Touch control pads. All Cisco Touch control pads do require a physical connection to the endpoints they are controlling. For endpoints that have a dual network interface card (NIC) port available, the Touch can be plugged into that available port. If the

To configure H.323 on a TC software-based endpoint, navigate to Configuration > System Configuration. Click the H.323 menu in the left column. NAT mode is off by default and should not be turned on. Under the Profile 1 settings, the first setting you will see is the Call Setup Mode. This setting can be configured as Gatekeeper or Direct, and Gatekeeper is the default setting. In direct mode, the endpoint will not register with any gatekeeper. It can still place calls, but only by the IP address of the destination endpoint. No RAS (Registration, Admission, Status) messages will be sent from or to this endpoint because it does not require a gatekeeper. Leave this setting as Gatekeeper. The next significant settings Profile 1 are the gatekeeper settings. Theythe areendpoint address and discovery. Address is theunder address of the gatekeeper you want to register with; in this case, it is the VCS. Discovery determines how the endpoint will locate a gatekeeper to try to register with. Discovery mode can be configured as Manual or Auto. If configured as Auto, no gatekeeper address needs to be configured. The endpoint sends out a GRQ broadcast to locate the gatekeeper, as mentioned toward the beginning of this chapter. Manual uses the address specified in the above field. Best practice suggests leaving this setting as Manual, which is the default. The last subheading under Profile 1 is H.323 Alias, and the options here are E.164 and ID. An E.164 alias, as defined by the ITU, is a numeric alias using digits between 0 and 9 and should be no longer than 15 digits long. Essentially, it is a phone number. The ITU ratified the parameters for E.164 alias for use with H.320 circuit-switched communications. However, E.164 aliases were carried over with the development of H.323 packet-switched communication, and the length of the alias is less significant. On TC software-based endpoints, an E.164 alias can be up to 30 digits long, although that makes for a long phone number to remember. ID represents an H.323 ID, which is the other type of alias that can be used with H.323 communications. H.323 IDs can use alphanumeric and special characters up to 49 characters long. In the past, a common use of H.323 IDs was to use a person’s name. Someone could dial “John” and place a call to John’s endpoint. Today, a more common use of H.323 IDs is to configure them in the form of a URI. Make no mistake: H.323 ID is not a URI. However, they can be configured in the form of a URI. In some production environments, customers configure both the E.164 alias and the H.323 ID. The E.164 alias is commonly used for internal calls, and the H.323 ID, in the form of a URI, is used for external calls. Figure 10-10 illustrates the H.323 configuration menus available on a TC softwarebased endpoint.

Chapter 10: Configuring Cisco TelePresence TC Software-Based Endpoints

233

Figure 10-10 H.323 Menus on a TC Software-Based Endpoint

Each of the settings discussed in this section must be saved before they will take affect. Once saved, the endpoint should register with the VCS immediately. To verify the registration was successful, navigate to Home. Under the H.323 heading, Status should show up as Registered, Gatekeeper should be the VCS address specified in the H.323 configuration setting, Number should be the E.164 alias, and ID should be the H.323 ID. When registering an endpoint with the VCS, an administrator can choose whether to use H.323, SIP, or both. Because the foundation for registering a TC software-based endpoint has been established for H.323, a close examination on how to register the endpoint using SIP with the VCS is needed. Again, the VCS does not provision settings to endpoints, so all SIP configuration settings need to be configured on the endpoint before it can register with the VCS. Navigate to Configuration > System Configuration and click the SIP menu in the left menu column. There are many more options available than are needed for a basic SIP registration. This section focuses on only the basic settings needed to register an endpoint with the VCS using SIP. All of these settings can be found under the Profile 1 section. The first configuration parameter listed under Profile 1 is the Default Transport. This setting can be configured as TCP, UDP, TLS, or Auto. If none of your calls should be encrypted, set it to TCP or UDP. If all calls should be encrypted, set it to TLS. If you want SIP calls to try encrypting first, but to connect anyway if they cannot, use Auto. The default setting is TCP. Another menu option is Type, which can be configured as Standard or Cisco. Standard should be used when registering to the VCS, and this is the default setting. This setting will change automatically to Cisco when registering to the Cisco Unified CM. Administrators should never need to change this setting, but it is a valuable setting of which to be aware.

CCNA Collaboration CIVND 210-065 Official Cert Guide

Below this setting is the Display Name. This name will display on the destination endpoint’s monitor when you connect. It will also be displayed when connecting through a multipoint control unit (MCU). If this setting is not configured, the URI address displays in its place. A little further down is the URI setting. This should be the URI address that users will dial when they are trying to connect to your endpoint. URI addresses must be in the form of Host@FQDN. The VCS will qualify the domain, and all SIP registrations will fail if the domain used in the URI address does not match a domain configured on the VCS. This is the marking difference between a URI and an H.323 ID. Because the H.323 ID is not actually a URI, the H.323 registration is allowed to register with a VCS regardless of what comes after the @. With SIP, however, the domain is a significant part of the alias and must qualify against domains listed on the VCS. Some time was spent in this chapter explaining what a SIP server is and how the SIP registrar and the SIP proxy are functions of the SIP server. To point a TC software-based endpoint to the VCS for SIP registration, the Proxy 1 address must be configured. Under Proxy 1, two settings are listed: Address and Mode. Mode for SIP is the same as Mode for H.323. It can be configured as Manual or Auto and determines how the endpoint will try to locate a SIP server (VCS) to register with. Leave this setting as Manual. Under Address, configure the address of the VCS. All the previously mentioned settings need to be saved for the configurations to take place. Figure 10-11 shows how the SIP configuration menus will display on a TC software-based endpoint.

Figure 10-11 SIP Menus on a TC Software-Based Endpoint

To verify the endpoint has registered, click the Home menu across the top of the page. Under the SIP heading, Status should show as registered, Proxy should be the VCS address, and URI should be the URI address configured on the endpoint.

Validating Network Settings Network settings are a critica l part of configuri ng any device. “If you can’t ping it, you can’t ring it” is the coined phrase that best describes the necessity of configuri ng these network settings appropriately . Some qual ifying questions that must be a nswered before configuring the network settings on a TC s oftware-based endpoint are, “What speed and duplex should be used, a nd should these settings be discovered aut omatically or statically as signed?” “How will VLAN di scovery be used, if it is used at all?” “Will DHCP be used or static IP addressing?”

The question pertaining to speed and duplex will be addressed first. The speed options available on TC software-based endpoints are 10 Mbps, 100 Mbps, and 1000 Mbps (or 1 Gbps). Duplex has to do with how nodes send and receive packets across a network, and the options are half duplex and full duplex. Both offer two-way communication, but half duplex only allows for communication to occur one direction at a time. Walkie-Talkies are perfect examples of half-duplex communication. What happens if both parties using a Walkie-Talkie try pressing the Talk button at the same time? Neither party will be able to hear what the other party is saying. Full duplex allows for a node to send and receive packets at the same time. In IP communications, only full duplex should be used. Using half duplex in IP communications will double the amount of bandwidth required because extra ports will need to be opened for two-way communication. Duplex is configured and displayed with the speed on TC software-based endpoints. The options available are Auto, 10half, 10full, 100half, 100full, and 1000full. Auto is the default setting and will use whatever speed the router specifies should be used. It is recommended by Cisco that Auto should be used. However, it is always good to verify what rate is actually negotiated. If speed and duplex are configured as Auto, but the status shows half duplex, the setting will need to be changed on both the endpoint and the router to full duplex. If this setting is only changed on one device and not the other, you could experience something called duplex mismatch. Telltale signs that duplex mismatch is occurring include registrations dropping, calls not connecting, or calls dropping in the middle of the call. Another potentially problematic component pertaining to network settings is VLAN usage. Endpoints in a Cisco Unified CM environment need to use tagged auxiliary voice VLAN. However, when TC software-based endpoints register with the VCS, the untagged data VLAN is used. Even when the untagged data VLAN is used, Cisco Discovery Protocol (CDP) will still discover TC software-based endpoints connected to a switch. However, this does not mean that the endpoint will automatically search for the voice VLAN. The VLAN mode on the endpoint must be set to either Auto or Manual. Auto will allow the endpoint to discover VLAN information using CDP. Manual required an administrator to manually set the tagged auxiliary voice VLAN numeric value. The VLAN mode is automatically changed to auto when the provisioning mode is changed to CUCM. (Review the previous section on registering TC software-based endpoint to the Cisco Unified CM for instructions on how to change the provisioning mode.) IP addressing information is required when any device wants to communicate across a network. The required components needed are an IP address, default gateway, and the subnet mask. Other optional network addressing information that could be used are DNS addresses and, if Option 150 is used, TFTP server addresses. IP addressing information can be delivered over DHCP, or they can be statically assigned. TC software-based endpoints will use DHCP by default. If an administrator wants to use static IP addressing, these settings can be changed. It is not recommended to change these settings from the web interface because once one component is changed, you may lose connectivity to the endpoint. The best option is to use the CLI with a serial connection or use the remote control. The commands that enable you to configure static network settings with the CLI are as follows: xConfiguration Network 1 IPv4 SubnetMask: 255.255.255.0 xConfiguration Network 1 IPv4 Gateway: “xxx.xxx.xxx.xxx xConfiguration Network 1 IPv4 Address: xxx.xxx.xxx.xxx xConfiguration Network 1 IPv4 Assignment: Static

Global phonebooks (also referred to as downloaded phonebooks) and corporate phonebooks (also referred to as centralized phonebooks) are received from TMS in different manners from each other and can only be used in a VCS call control environment. The big difference between these two types of phone books is that global phonebooks are downloaded to the endpoint, whereas corporate phonebooks are centrally located on TMS. Endpoints must be configured to subscribe to TMS before corporate phonebook entries are published to the endpoint. The advantage of global phonebooks is that if the endpoint loses connectivity to TMS, the endpoint still keeps the global phonebook entries. A disadvantage of global phonebooks is the capacity limitations of TC software-based endpoints. Another disadvantage of global phonebooks is directory entries are only as current as the last time the phonebooks were pushed to the endpoint. An advantage of a corporate phonebook is that entries are always current. Also, there is no limit to the number of entries a phonebook can contain because corporate phonebooks reside on TMS at all times. The disadvantage of corporate phonebooks is that if the endpoint loses connectivity to TMS, corporate phonebooks cannot be accessed. Both global and corporate phonebooks can be used on TC software-based endpoints at the same time, so there is no reason an administrator should have to choose which phonebook to use. No settings need to be configured on a TC software-based endpoint to receive global phonebooks. However, these endpoints do need to be configured with corporate phonebooks so that the endpoint knows where to subscribe to for phonebook entries. To configure corporate phonebook settings from the web interface of TC software-based endpoints, navigate to Configuration > System Configuration > Phonebook Server. The type should be set to TMS, and the URL should be configured as http://TMSServerIPAddress/tms/ external/phonebook/phonebookservice.asmx. Users can now access corporate phonebook entries using the remote control (Intelligent Proximity or Touch Controller) by selecting the green Call button. When users begin typing an alias (or participant name), entries will automatically populate based on the characters dialed. The arrow keys can be used to make a selection from the list.

Cisco TC Software-Based Endpoint Call Scenarios Users and administrators can call on TC software-based endpoints using the remote control, web interface, CLI Touch controller, or Intelligent Proximity. If the remote control of a Touch controller is used, pressing the green Call button will bring up calling options. When placing calls through the web interface, users need to navigate to the Call Control menu. Under the Contacts box, aliases can be entered in the Search or Dial field. Additional options include selecting entries from the Favorites, Directory or Resents categories. When an alias is dialed in the Search or Dial field, a callout window will appear to the right. Within that callout will be a green Call button and a Show Call Settings menu option. Selecting the Show Call Settings menu option offers additional Call Rate and Protocol options. Call rate is the bandwidth speed the call will request to use, and protocol options include Auto, H.323, and SIP. If the CLI is used to place calls, the command to use is xCommand Dial Number: . Though placing calls is a fairly intuitive task, several configurable options are available on TC software-based endpoints that relate to calls. Such options include Auto Answer,

CHAPTER 11

Cisco Legacy Edge Architecture When networking was first introduced, many companies were formed establishing different types of networks, each using a different language to communicate. Therefore, organizations were established to standardize how devices communicate between each other. Once businesses could communicate together, security had to be introduced to protect these businesses from cyber-attacks. This raised several more communication issues that took many years to resolve. Cisco has an iron-clad solution that allows business to communicate with one another, and with customers, in a secure environment. This chapter discusses Network Address Translation (NAT) and firewall issues that companies encounter within a collaboration solution. An overview of Cisco solutions that address these issues will help you understand the foundational components needed in a Cisco firewall-traversal solution. This solution enables remote and telecommuters to establish mobile and remot e access to infrastructure withi n an organi zation. You will also lear n how business-to-consumer communication ca n be established using the Cisco Jabber Guest solution. All of these components can be i nterlaced together with an expla nation on how different call mobility solutions function, and how they can be configured to establish a sing le-number-reach fo r users with multiple modes of communication.

packets are sent out, TCP requires a return communication. If a return communication is not received in a set amount of time, the packets are re-sent. NAT becomes an issue with collaboration devices for two reasons: ■

NAT does not allow communication to be initiated from outside the private network because the virtual ports can change with each new transmission that is created. So if two video endpoints behind different NATs want to communicate, one will never be able to discover the other. For example, if a device were to try to route to the private IP address of another endpoint, the transmission would fail at the source router because private IP addresses are not publicly routable. Alternatively, if the source device were to try to route to the public IP address of the far end router, once the packets arrived, the far end router would not know which device to route the packets to.

■

The second issue that comes with NAT has to do with UDP (User Datagram Protocol) transmissions. Whereas TCP communications require a response, UDP communications are unidirectional. Once video calls are set up using TCP, the audio and video packets are sent using UDP. Therefore, the one-way transmission has no way of knowing whether the endpoint residing behind the NAT server received the audio or video packets.

The IETF, who came up with the Session Initiation Protocol (SIP) communications protocol and NAT, also came up with the first solution that allowed communications between private LAN/WANs through a NAT server. That protocol is known as Session Traversal Utilities for NAT (STUN). After creating the RFC for STUN, The IETF came up with two other RFC protocols known as Traversals Using Relays around NAT (TURN) and Interactive Connectivity Establishment (ICE). Figure 11-1 illustrates how STUN can be used for NAT traversal. As illustrated in the scenario in Figure 11-1, the endpoint sends a STUN request through the default gateway to the STUN server located on the public network. The STUN server is listening on port 5060. The gateway forwards the request to STUN server and changes port 5060 to another port number. The STUN server records the address and port and sends a response back to the endpoint. This IP and port are now assigned to the requesting endpoint. When the endpoint establishes a session (for example, a SIP-based Voice over IP [VoIP] or video call with an external entity), it can notify the external entity to sends responses back on the public IP address and port assigned by the STUN server. Now the UDP connection can successfully be established between two endpoints without NAT issues hindering the connection. Although STUN is a great solution, it does not work properly with networks using Symmetric NAT. Symmetric NAT creates a new address and port mapping each time an internal host tries to connect to an external host. To resolve Symmetric NAT issues, the IETF came us with another protocol called TURN. TURN performs much like STUN; however, it uses a relay that STUN does not possess, allowing for server-reflexive addresses and SNATs (Symmetric NATs) alike. Because the TURN server is used as a relay, more bandwidth is required, and all media must go through the TURN server. Figure 11-2 illustrates how a TURN server can be used within a network.

Communications Mobile and Remote Access also allows the traversal communication to be leveraged for endpoint registration. Unified Communications Mobile and Remote Access uses the Expressway Edge as the traversal server that is installed on the public network or in a DMZ and Expressway Core as the traversal client that is installed on the internal network. The following connections must be enabled on the firewall: ■

■

SIP: TCP 7001

■

Traversal Media:UDP 36000 to 36001

■

■

to 61799 ■

Media: UDP 36012 to 59999

The external DNS server must be configured with collab-edge._tls. service records so that external endpoints can discover that they should use Cisco Expressway Edge for mobile and remote access. Service records for secure SIP are also recommended for deploying secure SIP calls on the Internet. The service records must point to the Cisco Expressway Edge server. The internal DNS server must be configured with a cisco-uds._tcp. service record so that internal endpoints can discover that they should use Cisco Unified CM for direct registration. Be sure that the uds service records are not advertised externally; otherwise, issues could result from clients not knowing where to register. When using Cisco Unified CM IM and Presence, a cuplogin._tcp service record is also required on the internal DNS. You must point all call-processing nodes to a Cisco Unified CM cluster fully qualified domain name (FQDN) when configuring the cisco-uds._tcp. service record. All Cisco Unified CM IM and Presence server clusters should be configured in the same manner when configuring the cuplogin._tcp. service record. The internal DNS records must be available to all internal endpoints and to Cisco Expressway Core. Unified Communications Mobile and Remote Access requires certificates for secure communication between endpoints outside the network and the internal Cisco Unified CM. Cisco has recently issued four new certificates to use in conjunction with the Expressway Edge or the VCS Expressway. Though these new certificates pertain to WebEx integration, Cisco recommends they be used regardless of whether WebEx is being used. These four certificated are not included in Table 11-3, which outlines the different certificate types needed and where they are needed.

Note It is important for users to be aware that by default, when a Jabber IM client is

being used, it will try to authenticate with WebEx Connect first, regardless whether the customer is using WebEx Connect. You can call Cisco, or your service provider, and have them disable it.

Jabber Guest Cisco has a new product available through the collaboration edge solution that helps businesses extend their reach to customers who may not have a video communication solution available. Cisco Jabber Guest helps customers interact with enterprise workers by using realtime communications that are high quality, standards based, and comprehensive. Enterprise workers can send a link to guests, who simply need to click a URL link, website link, or mobile application to start the interaction. This will start a WebRTC type of a session with the employee using a Cisco collaboration endpoint. Build these capabilities in to your website or mobile application with the included software development kits (SDKs), or use the Jabber Guest client experiences. With Cisco Jabber Guest, different user-friendly options still exist, like audio and video communication. Desktop- and content-sharing capabilities are not available currently, but receiving content is coming in a future release. Guest users are not required to enter a username or password because there is no account needed for those users to employ Jabber Guest. Cisco Jabber Guest allows organizations to leverage an already-existing infrastructure. There is a Jabber Guest server that needs to be deployed before these services are available. Also, the Cisco Jabber Guest solution requires a dedicated Expressway Edge and Expressway Core. Various deployment options exist with this solution, but the simplest way Jabber Guest works is in a Cisco Expressway Edge with single network interface card (NIC) deployment. Within the enterprise network resides the Cisco Unified CM, the Expressway Core, the Jabber Guest server. Endpoints register to thethese Ciscoendpoints Unified CM the Cisco and Unified CM still handles all the call control between and because the Jabber Guest client. The Expressway Edge server lives outside the internal firewall, possibly in a DMZ. Customers can launch Jabber Guest within their own network using a browser like Firefox or Google Chrome. When the customer launches a Jabber Guest call, the call setup signaling crosses the Internet to the Cisco Expressway Edge server. The Expressway Edge passes the signaling to the Expressway Core, and the Expressway Core first establishes a communication with the Jabber client server to determine how it should route this session. Then the Expressway Core communicates with the Cisco Unified CM. All call admission control settings are applied to this call before the Cisco Unified CM communicates with the collaboration endpoint that a call attempt is being made. Return call setup communication follows the same path in reverse order. Once the call is set up, the media flows from the Jabber Guest client to the collaboration endpoint and back again, through the Expressway Core and Edge. Figure 11-5 illustrates how the Cisco Jabber Guest solution works.

Each end user can configure Cisco Unified Mobility to his or her own specifications. To log in to the Self Care Portal on the Cisco Unified CM, navigate to https://CUCM name or IPaddress>/ucmuser. Enter the user login credentials when prompted. The Cisco Unified CM system administrator, who also controls what features are available, must set up use of the Self Care Portal before end users can configure their settings. However, once users log in, there are several functions they could potentially perform. End users can modify the mobile number, allowing a cell phone to ring when the primary number is dialed. End users can control the timers, which are used to control the mobility algorithm. Time schedules can be established that determine which devices will ring during different hours and days. For example, Monday through Friday from 9:00 a.m. to 5:00 p.m., a user’s mobile phone, DX70 desk phone, and Jabber client will all ring for 30 seconds; then the call will redirect to voice mail. All other hours, the call will go directly to voice mail. Certain callers can also be blocked from calling Unified Mobility devices. Similar to Unified Mobility, FindMe is a call mobility feature for Cisco VCS-centric environments. Using FindMe requires an option key. The operation of FindMe is very similar to Cisco Unified Mobility. One significant difference between the two call mobility features is the alias used to extend reachability. Cisco Unified Mobility uses the alias of the primary endpoint to initiate the transfer of the call. FindMe requires a FindMe ID to be configured for the FindMe account, which is the dial-able alias to be used. When a user dials the FindMe ID, the VCS initiates a call-processing order. Within the call-processing order, the alias dialed is identified as a FindMe ID, and the call transfer behaviors will be based on the FindMe account with which it is associated. The first behavior the VCS looks for in a FindMe account is what endpoint, or endpoints, the call should be transferred to first. There are two alternate options of transfer based on the behavior of the first call transfer. If the call is busy another endpoint, or endpoints, can be specified for the call to be transferred. Alternatively, if the call rings for a specified duration of time without being answered, another selection of devices can be specified to transfer the call. Whereas Cisco Unified Mobility has a Self Care Portal for users to configure their Unified Mobility settings, Cisco FindMe has a user portal as well. How this portal is accessed will depend on how the VCS-centric environment is set up. FindMe is a feature of the Cisco VCS. Navigating to the URL or IP address of the Cisco VCS will present two login options: Administrator or User. The User login is how FindMe uses can log in to manage their own FindMe accounts. Cisco TelePresence Management Suite (TMS) can play an active role in how FindMe works. If TMS Provisioning Extension (TMSPE) integration is used, the User login portal through the VCS goes away, and a new User portal is made available through TMS. FindMe accounts are created initially by the VCS administrator, and then configured by users to their desired specifications. Because organization may need to support thousands of FindMe accounts, TMS integration can be used to provision a FindMe template, which can be mass distributed to everyone within an organization. Figure 11-6 illustrates the FindMe user portal on the VCS as it compares to the FindMe user portal on TMS.

Summary It is said, “Invention is 10 percent sweat and 90 percent necessity.” Networks have evolved significantly over the past three and a half decades. Much of the development in protocols and technologies has derived from needs that surfaced throughout this development process. Some of those needs have been addressed in this chapter, like the limitation of IPv4 that led to the development of IPv6 and NAT. NAT created other issues with communication across networks, specifically pertaining to voice and video over IP. The protocols that were developed by the IETF to overcome NAT traversal were STUN, TURN, and ICE. Although these protocols did resolve one issue, they simply bypassed a second issue: firewall traversal. A proprietary protocol came about, called Assent, that resolved both the NAT and firewall issues, and maintained a secure environment for corporate networks. The Assent protocol became the basis for the H.323 traversal standards of the ITU called H.460.17, H.460.18, and H.460.19. All of these new standards and protocols led the way to the development of new technology products as well. Cisco has two call control solutions available for various industry needs, and there are also two traversal solutions that exist. For a Cisco VCS-centric environment, there is the VCS-traversal solution. This solution features the VCS Control and VCS Expressway as the traversal components needed. Within a Cisco Unified CM-centric environment, there is the collaboration edge solution. This solution features the Expressway Core and Expressway Edge as the traversal components needed. The Cisco Jabber Guest option offers an addendum to the collaboration edge solution. Cisco Jabber Guest allows businesses to extend their reachability to other businesses and customers who may not support a video communications solution. Another technology developed over the years is call mobility. Cisco solutions offer two modes of accomplishing call mobility. In a Cisco Unified CM-centric environment, the Cisco Unified Mobility feature can be leveraged to allow employees to be contacted with a single number reach. In a Cisco VCS-centric environment, this is accomplished through a feature called FindMe. Although the topics discussed in this chapter are beyond th e scope of CIVND2, a ba sic understanding of them is expected by Cisco. This chapter has included more detail about these features and products to help prepare you with future certifications you may pursue, and to familia rize you with products and solutions being used in Cisco deploymen ts globally.

Operating and Troubleshooting Cisco TelePresence Endpoints It is a wonderful, yet odd, feeling to install a Cisco TelePresence solution where everything works perfectly. It is an odd feeling because Cisco TelePresence endpoints are complex systems that involve many st ate-of-the-art peripherals for audio, video, and collaboration experience, and often th e vary ing pieces and parts do not always work the way they are supposed to. Even after everything is installed a nd tested to working order , the human element will inevitably break somethi ng down the line, requiring someone to troubleshoot the issues at hand. Th is lesson wil l guide adminis trators to be profi cient with var ious tools needed to operate and potentially troubleshoot these complex systems in a network environment. This chapter describes the various tools that are used to perform regular tasks such as backup, restore, and performing upgrades. Other tasks described in this chapter include how to view call statistic information and pull logs to aid in troubleshooting Cisco TelePresence collaboration endpoints.

package file you downloaded from Cisco. Click Upgrade. The system starts downloading the file to the endpoint’s local disk and then performs the upgrade from that disk. Do not use the endpoint during the upgrade; doing so might interrupt the process. The endpoint reboots twice during the upgrade. The first reboot is used to finalize the endpoint upgrade. The second reboot is to finalize the camera upgrade. When the upgrade is successfully completed, a message appears. This process can take up to 30 minutes. On the same upgrade page of the web interface, an administrator can add option keys for new features as required. Option keys allow for extended functionality of the system and do not require reboot when added. You might have several option in your system. Review Chaptera 7, “Cisco TelePresence Endpoint Characteristics,” forkeys information about available TC software-based endpoint option keys. If you need to downgrade the software on Cisco TelePresence TC software-based endpoints, you may need to open a Cisco TAC case to obtain special release keys. There is another option to back up, restore, and upgrade TC software-based endpoints. Cisco TelePresence Management Suite (TMS) is a complete management tool that enables administrators to manage an entire video network from a single interface. Be aware that backups cannot be scheduled, nor should they be. Consider if an endpoint were scheduled to be backed up by TMS and someone changed settings on that endpoint before the backup took place; in this case, issues relevant to those changes would be backed up as well. However, using TMS to perform these tasks offers many benefits. Though a backup cannot be scheduled, a restore can be. After endpoints have been backed up, an administrator can schedule that those endpoints are restored once a day or once a week. Two of the main benefits of using TMS for upgrades are the ability to perform bulk upgrades with a single click of a button and upgrades can also be scheduled to occur at a time when the systems will not be in use, such as on a Saturday at midnight. The subject of how to use TMS to perform these tasks is beyond the scope of the Cisco CIVND material. However, further discussion on Cisco TMS will follow in later chapters.

Isolating and Identifying Issues on Cisco TelePresence TC Software-Based Endpoints Troubleshooting issues on Cisco TelePresence TC software-based endpoints can be a particularly cumbersome task because the call control mechanism used could be the Video Communication Server (VCS), which supports H.323 and SIP, or it could be the Cisco Unified CM with SIP. The tools used for troubleshooting may depend on the issue type being experienced or the type of issue needing fixed. There are different tools available for troubleshooting registration issues, call setup issues, or media issues. The web interface, onscreen display, and the CLI provide call statistics that include packet loss, jitter, and delay statistics for incoming and outgoing audio and video channels. Figure 12-2 illustrates what the call statistics look like during a video call on an SX10 endpoint.

If IP connectivity were working across the network, the next step to troubleshooting registration issues on TC software-based endpoints would be to look for nonmatching configuration settings between the server and the endpoint. For Cisco VCS registration issues, you need to make sure that the protocol that is used (H.323 or SIP) is enabled at both the endpoint and the server. With H.323, calls are possible without registering to a gatekeeper if the call setup mode is set to Direct. In direct mode, the endpoint never tries to register to a gatekeeper. If the desired outcome is for the endpoint to register to the VCS, the call setup mode will need to be set to Gatekeeper. In gatekeeper mode, calls are not possible until the endpoint registers. The discovery mode on the Cisco VCS determines how the endpoint will try to discover the call control server for both H.323 and SIP. If the discovery mode is set to Automatic, the TC software-based endpoint sends out a broadcast request searching for any call control device to which it can register. The first call control server to respond is where the endpoint will try to register, which may not be where the administrator intended the endpoint to register. If there is no response, registration fails. Best practice suggests setting the discovery mode to Manual and entering the specific address of a call control server to which the endpoint will try to register. H.323 registration requests always use UDP port 1719 for Registration Request (RRQ) messaging to a gatekeeper. SIP, however, could use UDP port 5060 or UDP over TLS 5061. Make sure that the correct matching transport protocol is set at both the endpoint and the server for SIP. Note that discovery mode has no bearing on TC software-based endpoint registration to the Cisco Unified CM. Issues registering to the Cisco Unified CM are typically caused because the voice VLAN was not learned from the switch, Dyna mic Host Configuration Protocol (DHCP) did not provide the correct IP settings or the right TF TP server address through Option 150, IP connectivity to the Cisco Unified CM server or Cisco TF TP server is broken, or the endpoint is provisioned incorrectly. This is a lso true for Cisco TC s oftware-based endpoints trying to register to the Cisco Unified CM. V erify that external m anager mode is set to CUCM . If you configure the Cisco TFT P server IP address m anually, verify that the correct address is s et in the Cisco TelePresence TC software-based endpoint External Manager Address field. Also verify that HTT P is chosen for th e external man ager in the advanced settings configuration. Provided the endpoint has registered to the call control server, the next issue that could be encountered relates to call setup. Because of the complexity of the setup, a great variety of problems can be experienced when setting up a call with a Cisco TelePresence TC software-based endpoint. There are few tools on the endpoint itself that can help detect call setup issues. Most of the tools reside in the Cisco Unified CM or the Cisco VCS, which are beyond the scope of this class. Verify that the dial plan is correct and that calls can be successfully routed by using it. Take a screen capture of system configuration settings, status messages, and debug files, and then escalate call setup issues to a call control administrator. These administrators can verify CAC settings used to set up bandwidth limits and call privileges that can accommodate a certain number of calls. Media issues ca n be as complex as cal l setup issues to troubleshoot be cause ma ny moving parts can i mpact audio and video packets sent and received. Video input devices include cameras , computers for content sharing, document cameras , and video-playing devices.

The Sysop Log tab displays system operation messages, including call information, call statistics, and call errors for the Cisco TelePresence System. As many as 20 individual files are saved on the Cisco TelePresence System, and each file can contain as many as 100,000 characters. To download the log files, click the Download Sysop Files button at the bottom of the page. The prompt that comes up presents two options: open to view the log files or save the log files to the local disk on your computer. If the option to open the log file is chosen, the last 100,000 bytes of the log are shown, and all available systems operation log files are downloaded. The Files tabfrom allows administrators to download log files capture new log files. YouLog can choose three download options by selecting theorappropriate radio buttons. None is the default, and no log files are captured unless a download option is chosen. The Download Existing Log Files option allows you to download existing log files. Click this radio button and then choose a problem from the Select Problem Type drop-down list to download logs. The drop-down list contains the following problem types: Audio (Speakers, Microphones), Video (Displays, Cameras), Projector, LCD, Document Camera, Phone, Recording, and Other/Unknown. When you click Download Existing Log Files , the system shows the message “A WinZip download will start within several minutes. Please wait.” The File Download window appears, prompting you to open or save the file. The other option available within the Log Files tab is to Capture New Log Files. After you choose from the Select Problem Type drop-down list and click Capture New Log Files, the system displays the message “Collecting Cisco TelePresence System log files. This process may take several minutes. Please wait.” The File Download window appears, prompting you to open or save the file. When you capture new log files, the system combines and compresses all existing log files from the codec. The Log Files tab displays the status of the log capture, including the percentage of completion. The SIP Messages tab displays all SIP messages sent and received by the CTS software-based endpoint. You can filter the SIP messages to display a specific type of message in the SIP log file. You can also choose the number of messages to view at one time. Double-clicking a SIP message from the list opens the SIP Message Details dialog box for detailed message reports. You can do the same thing by highlighting the SIP message and clicking Details. Viewing real-time call statistics is an important function on any endpoint. From the Cisco CTS web interface, choose Monitoring > Call Statistics. The Real Time Call Statistics section lists the details of an in-progress call, including the connection status, registration status, and local directory number. There is also a Historical Call Statistics (Not Including Current Call, If Any) section that lists historical information about past calls. There are also Audio/Video Call sections that list details about a call, such as audio stream statistics of an audio/video call, video stream statistics of an audio/video call, and audio-only call stream statistics. These call statistics show both transmit and receive call information. Other critical information displayed includes local and remote endpoint IP address information, average latency, differentiated services code point (DSCP), and class of service (CoS) quality of service (QoS) markings.

that is required for successful registration, such as SIP and HTTP traffic. Make sure that the UDP and TCP SIP ports 5060 and TCP HTTP port 6970 are open. If there were no network-related issues found, the next step an administrator must examine is whether the endpoint has obtained the appropriate IP address of the Cisco TFTP server. This IP address is usually obtained through Option 150, although it can be configured manually. The Cisco Unified CM cluster might also be causing issues if the endpoint is not configured and automatic provisioning is disabled or if required services are not responding. Oftentimes, CTS software-based endpoints show as registered to the Cisco Unified CM, but the touch panel does not work. This issue is usually due to the panel-to-system communication. The touch panel automatically obtains its IP address from the endpoint built-in DHCP server. Make sure that the server process runs normally using the CLI command utils service list. When you display the system status at the touch panel, the panel should show the correct IP address. Another issue that could prevent the touch panel from functioning properly is related to the firmware load file. When the CTS endpoint receives firmware bin files from the TFTP server some of the bin files contain the firmware for the touch panel, which the CTS endpoint is responsible for delivering. If the endpoint performs an upgrade during the registration process, something could have prevented the CTS endpoint from delivering the appropriate files to the touch panel. Try rebooting the endpoint to reinitiate this process. If that does not work, check that the Cisco Unified CM has the appropriate files upload for the version the CTS endpoint is running. There should be three files listed (two for the CTS endpoint, and one for the touch panel). If you experience degraded audio quality or the call is dropped completely, the Cisco TelePresence endpoint might be experiencing packet loss or packet jitter for an extended period. Verify packet loss and jitter through system operation logs or live call statistics from the CLI or web graphical user interface (GUI). Check the network path to determine whether jitter or packet loss is observed. If users experience choppy audio during bidirectional discussions, the issue might be caused when the audio echo canceller briefly mistakes one of the speech patterns for noise and cancels it, resulting in choppy audio. The audio from the remote side is slightly attenuated before being played out to the speaker. The echo-cancellation feature removes some of the sound from the talkers during the bidirectional discussions. Check whether there has been a change in the echo path. For example, someone may have moved the speakers or microphone, or there could be a laptop or other device directly placed in front of the microphone. Otherwise, this behavior is expected. The existing filter parameters should be enough to cancel the sound from the speaker. However, during bidirectional discussions, echo cancellation always removes some sound from the talker. High CPU or resource saturation can cause hearing echo. This situation might cause audio-missed interrupts on the endpoint. To get rid of the echo, you can perform a hold or resume of the call or redial it completely. When you hear echo, the most common issue is the room acoustic environment. Rarely, the issue is an audio port or microphone issue. To mitigate the issue, you can install an acoustic panel, or you can put in some furniture or plants and make sure that the audio volume is set to medium. Check the microphone and audio port. Unplug or mute the suspected microphone. If the problem persists, the microphone or that audio port is probably the issue. Swap the microphone for another one and see whether the problem follows the microphone or the codec. Plug only one microphone into an audio port at a time and continue through all the microphones and audio ports to

isolate the problem. Another cause for media issues on any endpoint has to do with duplex. Video endpoints must use full duplex. Check that the switch ports, endpoints are connected to and ensure they are not using half duplex. In most cases, autonegotiation will result in full duplex being used, but this is not always true, which is why it is always good to check.

Using the Cisco DX Series Problem Reporting Tool The Cisco DX650 includes an integrated Problem Report Tool to provide support for device-related issues. To access the tool, choose Settings > About Device. The first page provides information about the endpoint including thethe model number, version,diskernel version, and build number. When you scroll to second page,Android the information played includes the active load, last upgrade, active server, and standby server. To report a problem to Cisco, choose Cisco Collaboration Problem Reporting Tool. Users can issue a notification from the device by providing the following information: ■

Select the date that the problem was observed. This field is autopopulated with the date the tool was invoked, but it can be changed if needed.

■

Select the time that the problem was observed. This field is also autopopulated with the time the tool was invoked and can be changed.

■

Select the problem application. If you are unsure of the application that had the problem, choose None.

■

Enter a problem description. Include a concise description of the behavior that was observed.

■

Enter a customer support e-mail address.

Tap Create Problem Report when finished.

Isolating and Identifying Issues on Cisco Jabber Video for TelePresence The best tools available to aid in troubleshooting Cisco Jabber Video for TelePresence are the Cisco VCS and Cisco TMS because they completely control the Jabber Video for TelePresence client. The means of using the VCS and TMS for troubleshooting goes beyond the scope of the Cisco CIVND2 course; however, Cisco Jabber Video for TelePresence does provide error logging that can be used during the troubleshooting process when registration issues are experienced. Before these logs are used to troubleshoot registration issues, the following information should be verified first: ■

The computer that Cisco Jabber Video for TelePresence is installed on must have IP connectivity to the Cisco VCS. Use ping and traceroute from the PC to verify the IP connectivity.

■

If there is a firewall or access control list along the IP route, ensure that it does not block SIP traffic at TCP 5060, UDP 5060, or TLS 5061 in either direction.

■

Make sure that the sign-in window shows the correct VCS Control or VCS Expressway address and domain.

■

Verify that the login credentials are correct for signing in.

Summary Understanding how to pull log information and maintain endpoints is critical in any production environment, and becomes an asset in troubleshooting issues when they occur. This chapter focused on how to use the onscreen display, the web interface, and the CLI to collect log information on Cisco TC software-based endpoints. All system information is written to and stored in the Current and Historical log files. This information can be expanded using debug commands to offer detailed call traces, which will aid in troubleshooting call setup issues. Administrators should now understand how to perform maintenance on TC software-based endpoints, including how to back up and restore the configuration settings of an endpoint and how to perform an upgrade. Key issues have been identified on TC software-based endpoints that can cause registration, calling, and media issues. These endpoints have tools embedded in them that you can use to troubleshoot these issues. Cisco CTS software-based endpoints have three logs available that can be accessed through the web interface. These logs continually capture relevant information about the endpoint and can be used to troubleshoot issues when they occur. Because CTS software-based endpoints are controlled entirely by the Cisco Unified CM, troubleshooting steps for these endpoints have been identified in the same manner as troubleshooting other UC or collaboration endpoints within a Cisco Unified CM-centric environment. Cisco Jabber Video for TelePresence has some tools available locally on the hosting computer that can be use to aid in troubleshooting issues relevant to the soft client. However, because Jabber Video for TelePresence is dependent on the Cisco VCS and the Cisco TMS servers, they are the best tools available for troubleshooting Jabber Video for TelePresence issues. Most issues regarding this soft client will need to be escalated to the VCS or TMS administrator.

CHAPTER 13

Cisco Multipoint Solution Up to this point, the discussions in this book have primarily centered on endpoints. However, even with the plain old telephone system (POTS), the need to conference multiple devices into a single call have been in demand. In video communications, this option is called a multipoint conference. There are different ways of hosting a multipoint conference, whether an endpoint has the ability to host the call or an external multipoint control unit (MCU) is used to host the call. This chapter discusses the main MCU options available in a Cisco collaboration network. You will learn the definitions of and differences between multipoint, multisite, and multiway. Finally, you will learn about ad hoc calls with use case explanations of when ad hoc calling is used within the Cisco collaboration solution.

way and reboot, this time using the new static IP address assigned to it. When the Cisco TelePresence MCU has finished the reboot process, the administrator can web into the unit through a web browser. To finalize the initial setup of the Cisco TelePresence MCU, a few settings need to be verified, and possibly changed, through the web interface. Open a web browser and navigate to the IP address of the MCU. Log in with the username admin and leave the Password field blank. Figure 14-1 shows the menus that are available once an administrator logs in to the MCU.

Select the Network menu, and under the Port A submenu, scroll down to the Port A IP Status section. Verify that the correct IP address information is displayed. Scroll down farther to the Port A Ethernet Status section and verify that the Duplex is negotiated at Full Duplex. If the Duplex is negotiated at Half Duplex, this setting will need to be changed on the MCU and on the router from Automatic to Full Duplex. Changing this setting in both places will prevent duplex mismatch from occurring. Figure 14-2 identifies the network settings available through the web interface.

Next, click the DNS menu and enter the hostname and domain for the MCU. Together these two settings make up the DNS A record as it would appear within the DNS server. A secondary DNS address can be entered at this time as well. The hostname is also the system name. This will appear in TMS after the MCU is added. Click the Update DNS Configuration button. Verify that the information is displayed correctly under the DNS Status section. Figure 14-3 identifies the DNS settings available through the web interface. Click the Services menu. Ensure that all the services you intend to use are enabled by checking the box beside the port number, and ensure that the port numbers match the ports used within your network. Default port numbers are displayed automatically. The TCP services available on the MCU include HTTP, HTTPS, Incoming H.323, SIP (TCP), Encrypted SIP (TLS), Streaming (Windows Media Player), Streaming (other), FTP, and ConferenceMe. Streaming and ConferenceMe are not available in the Cisco TelePresence MCU 5300 series. The UDP services available on the MCU include SNMP, SIP (UDP), H.323 gatekeeper, and tunneled media. Simple Network Management Protocol (SNMP) is used by the TelePresence Management Suite (TMS) to manage the Cisco TelePresence MCU. SIP (UDP) and H.323 gatekeeper are used for registration to the Cisco Video Communications Server (VCS). Figure 14-4 identifies the Services menu settings available through the web interface.

TANDBERG, they developed another MCU based on the Codian product called the 5300 series, removing the built-in gatekeeper along with some other functions, such as the streaming feature. If you want to register the Cisco TelePresence MCU to the Cisco VCS using H.323, do not use the Gatekeeper menu. This feature is disabled by default. Enabling this feature and registering the MCU to the Cisco VCS will cause routing issues. To register the Cisco TelePresence MCU to the Cisco VCS requires the administrator to click the Settings menu. Under the Settings menu, click the submenu called H.323. Under this menu, configure the following settings: 1. 2.

H.323 gatekeeper usage: Enabled. H.323 gatekeeper address: IP address of the VCS .

3.

Gatekeeper registration type: There are several choices under the gatekeeper registration type. Using the information button in the top right corner, indicated by an i, will open another page with descriptions to aid in finding out which type to use.

4.

Ethernet port association: Select the port (A or B) and IP type (IPv4 or IPv6) you are using.

the conference ID, there is a way to ensure that the caller still has options rather than just being disconnected from the call attempt. To resolve this issue, you need to configure the MCU service prefix. The MCU service prefix will register to the VCS. Any alias dialed that begins with this prefix is routed to the MCU regardless of the remaining digits. Because all calls beginning with that prefix are routed to the MCU, the MCU must be configured with how to deal with these calls when they come through. To configure this setting, click the Conferences tab, scroll toward the bottom of the page to the Incoming Calls to Unknown Conferences and Auto Attendantssetting, and select the desired parameter. Figure 14-8 illustrates the Incoming Call to Unknown Conferences And Auto Attendants menu options.

Figure 14-8 Incoming Call to Unknown Conferences and Auto Attendants Menu Options

The options are as follows: ■

Default Auto Attendant: Will route calls to the default auto attendant.

■

Disconnect Caller: Will drop the call. Normal call clearing will be displayed as the rea-

son the call was dropped in the VCS. ■

Create an Ad Hoc Conference:The MCU will create a new conference using the alias

dialed as the conference ID. After the MCU service prefix has been configured and registered to the Cisco VCS, when endpoint 5004 dials 85008, the VCS will only look at the 8, strip the prefix, and route the call to the MCU. The MCU will then perform the task configured in the Incoming Calls to Unknown Alias or Auto Attendants setting. In this scenario, the MCU creates an ad hoc conference with a conference ID of 5008. Figure 14-9 illustrates how this process works.

Figure 14-10 SIP Settings on the Cisco TelePresence MCU

Cisco TelePresence MCU Basic Setup for Cisco Unified CM Registration In a deployment in which the Cisco TelePresence MCU is registered to the Cisco Unified CM, the MCU acts as a media resource for the Cisco Unified CM. Media resources are services that allow the Cisco Unified CM to perform functions, like transcoding and music-on-hold. In this case, the service the Cisco Unified CM offers is multipoint conferencing. Deploying an MCU with the Cisco Unified CM only allows no support for scheduling. Instead, the MCU can be used for ad hoc or rendezvous conferences. It is important to note, however, that the Cisco TelePresence MCU can only be used as either an ad hoc conference resource or a rendezvous conference resource. A single MCU cannot fulfill both functions. This section discusses how to configure the Cisco TelePresence MCU as an ad hoc bridge. If the Cisco TelePresence MCU is deployed as a rendezvous conference bridge, and TMS is used to manage the MCU, conferences can be scheduled through TMS. To register the Cisco TelePresence MCU to the Cisco Unified CM, you need to configure the following settings. Media Port Reservation needs to be set to Disabled. When enabled on the MCU, this setting requires scheduled conferences to specify the number of ports needed. This ensures ports are available at the time conferences are scheduled to launch. If media port reservation is enabled in a typical deployment, the native ad hoc function on the MCU is disabled. Also, extending conferences on the MCU will not be allowed. This setting

The media resource group now needs to be placed within the appropriate media resource group list. Go to Media Resources > Media Resource Group List and click Add New. Create a name and move the previously created media resource group into the Selected Media Resource Groups area, and then Click Save. Media resources in the MRG, and MRGs in the media resource group list, will be used based on the order they are listed. Administrators should be very careful what order is used. Also, Cisco Unified CM is used for both voice and video communications, and each may use different resources. Therefore, best practice is to create a separate MRG and media resource group list (MRGL) for voice and video resources. Figure 14-14 illustrates how to configure an MRGL.

Figure 14-14 Adding MRG to MRGL

The media resource group list now needs to be attached to a device to be able to make use of the MCU for ad hoc conferencing. Go to Device > Phone and select a device. Choose the MRGL that you created earlier. Click Save and Apply Configuration when finished. Rather than adding the MRGL to every endpoint on the Cisco Unified CM, it can be added to a device pool instead. Every endpoint that is part of that device pool will automatically use the MCU as the media resource for ad hoc conferences. To add the MRGL to a device pool, go to System > Device Pool. Click an existing device pool, or click New to create a new one. Scroll down under the Roaming Sensitive Settings section and select the appropriate MRGL from the Media Resource Group List menu. Because some devices may already be using this device pool, select Save and Apply Configuration when finished. Figure 14-15 illustrates how to add an MRGL to a device pool.

CCNA Collaboration CIVND 210-065 Official Cert Guide Step 3.

Entering the PIN is an option that is enabled under the global conference settings. The use of a PIN can be enabled as an option or a requirement. If a PIN is enabled as an option and you are prompted to create a PIN but do not want to create one, waiting for a set duration of time will take you into the conference without PIN protection. If a PIN is required, the creator of the conference cannot start it without creating a PIN first. When prompted, create the PIN and press #. You will then be connected to the conference.

Other participants can dial directly into the created conference using the conference ID used to create the ad hoc conference. An alternative to ad hoc conferences can be scheduled in advance. On the web interface of the Cisco TelePresence MCU, click the Conferences menu. Four submenus will be displayed. Under the Conference List submenu, there are three sections: Active Conferences, Scheduled Conferences, and Completed Conferences. Figure 14-16 illustrates how this menu will appear.

Figure 14-16 Conference Menu on Cisco TelePresence MCU

Beside the Scheduled Conferences section, click the Add New Conferencebutton. The only configuration field that is required is the Name field. Enter a name for your conference. If you want participants to be able to dial directly into the conference, a numeric ID must also be configured. This scheduled conference can be protected with a PIN as well.

Figure 14-18 Cisco TelePresence MCU Conference Management

As shown in Figure 14-18, the conference details page can be used to verify the connected call status parameters. The relevant headings above the Participants section are used to verify status details: the type of the call; participant name or alias; and status, which details the connection time, transmit and receive codecs, resolutions, and bandwidth rates. The headings marked Importance and Mute allow administrators to assign chair control, mute the audio, and mute the video of each participant. The submenu tabs at the top of the page allow conference administrators to change settings like the layout all participants will use, and a text message can be sent to all participants in the conference, which will be displayed on their monitors. If an administrator were to click the blue hyperlink of a participant under the Participant heading, a new list of submenus would be accessible. From here, conference administrators can customize settings for that particular participant, send private text messages to their endpoint, and even view statistic and diagnostic settings specific to their connection with the MCU. The next section focuses more on what information can be obtained using the Statistics and Diagnostics tabs for participants. Figure 14-19 illustrates the submenu tabs available when a specific endpoint is selected.

Using the Statistics tool, an administrator can see the actual bandwidth that is used and jitter, packet errors, and the codec that is being used. Clicking the Diagnostics tab will display capabilities exchanged between the endpoint and the MCU. At the top of the page is a Status section with general call information like send and receive bandwidth rates. Below that is the Endpoint-Supplied Information section that displays the system name, E.164 alias (when applicable), product, and version. The third section is Media Capabilities. This section lists all the audio, video, and other codecs that were sent to the endpoints and received from the endpoint.

If an endpoint is unable to call into a conference, it could be a network-related issue preventing connectivity between that endpoint and the MCU. A tool on the MCU enables administrators to test the connectivity to any other device within the network. Click the Network main menu and the Connectivity submenu to access this tool. In the box beside Remote Host, enter the IP address of the device you are testing connectivity to, and then click the Test Connectivity button. The MCU will run a ping-route to that device and display the information in the window to the right.

Summary After completing this chapter, you should understand how the Cisco TelePresence MCU is configured, operates, and the native tools available on the MCU for troubleshooting used within your environment. This chapter examined how to install a Cisco TelePresence appliance MCU. After an MCU is installed, configuration settings need to be set up to register to the Cisco VCS, which supports both H.323 and SIP registration from the MCU. A unique set of configuration settings need to be configured on the MCU for registration to the Cisco Unified CM. The MCU does not actually point or reach out to the Cisco Unified CM for registration. Adding the MCU as a media resource on the Cisco Unified CM will establish registration. This chapter also covered how to create and configure both ad hoc and scheduled conferences and how to manage conferences after they have started. This chapter also assessed different logs and tools available on the MCU that you can use to troubleshoot issues as they develop.

CHAPTER 15

Cisco TelePresence Server The race for the best telepresence experience brought about much great advancement in the video telecommunications (VTC) industry. Cisco developed the Telepresence Interoperability Protocol (TIP) and made it open source. It is now widely used cross-vendor around the world. Cisco also developed the CTS 3000 series Immersive TelePresence Room Solution that sent other vendors scrambling to compete. Shortly after the CTS 3000 came out, TANDBERG developed the T3 Immersive Room Solution, and Polycom acquired a company that had an immersive room solution as well. With all these great multiscreen, multi-endpoint room solutions coming out, a chasm was created between the immersive telepresence solutions and the single-screen, single-endpoint products. That is what prompted TANDBERG to develop the TelePresence Server. The TelePresence Server is a multipoint control unit (MCU) that understands the difference between single-screen and multiscreen systems. It also handles TIP autocollaboration. This one product revolutionized the VTC industry and paved the way for many more advancements, which everyone is still witnessing today. This might be the pinnacle product that prompted Cisco to purchase TANDBERG. This chapter covers how to install a Cisco TelePresence Server, configure the server to register to the VCS and interoperate with the Cisco Unified CM, create and manage conferences, and examine the logs available on the Cisco TelePresence Server that you can use to aid in troubleshooting call-related issues.

TelePresence Server has shut down,” enter the command boot. This initiates a process where the TelePresence Server will shut down the rest of the way and reboot, this time using the new static IP address assigned to it. When the Cisco TelePresence Server has finished the reboot process, the administrator can web into the unit through a web browser. The settings that need to be configured from the web interface to finalize the initial setup of the Cisco TelePresence Server are similar to the MCU, discussed in the preceding chapter. However, the look and feel of the web interface of the TelePresence Server is different, as are some of the menu options. Figure 15-1 shows the menus that will be available when an administrator logs in to the Cisco TelePresence Server.

Figure 15-1 Cisco TelePresence Server Main Menus

Notice in Figure 15-1 that although the look of the web interface is different from that of Cisco TelePresence MCU, the menu structure is very similar. To access the web interface, open a web browser and navigate to the IP address of the TelePresence Server. Log in with the username admin and leave the Password field blank. Navigate to Network > Network Settings, and under the Port A IP Status section verify that the correct IP address information is displayed. Scroll down to the Port A Ethernet Status section and verify that the Duplex is negotiated at Full Duplex. Next, navigate to Network > DNS, and enter the hostname and domain for the TelePresence Server. Together these two settings make up the DNS A record as it would appear within the DNS server. A secondary DNS address can be entered at this time as well. The hostname is also the system name. This will appear in TMS after the TelePresence Server is added. Click the Update DNS Configuration button. Verify that the information is displayed correctly under the DNS Status section.

call traces on SIP, H.323, Binary Floor Control Protocol (BFCP), and eXtensive Conference Control Protocol (XCCP) communications. H.323 is not available in virtual and 300 series TelePresence Servers. This should not be enabled except at the time an issue needs to be traced to find the root cause. The information is stored locally on the TelePresence Server. Because this log contains a high level of information, it can fill up very quickly. If the log were to fill up, it would affect the performance of the TelePresence Server. This information can be stored on a remote server using the Syslog submenu. The event display filter controls the level of trace the Protocols log provides. The CDR log is a call detail record that shows all participant interaction with conferences on the TelePresence Server. The API Clients submenu can be used to show the 10 most recent application programming interface (API) clients that have made requests to the unit. Any clients in the list that have not made an API request in the past 5 minutes will be grayed out. Information provided under API Clients includes client IP, time since last request, last request method, last request user, and requests received since last reset. All of these logs can be downloaded in Extensible Markup Language (XML) format and can be manually deleted if they become too full. Diagnostics information and system logs can be downloaded by navigating to Status, scrolling to the bottom of the page, and clicking the related hyperlink provided. This is generic information representing the whole TelePresence Server. If an endpoint is unable to call into a conference, it could be a network-related issue preventing connectivity between that endpoint and the TelePresence Server.

Cisco TelePresence Management Suite Up to this point, this book has focused primarily on endpoints. As to the maintenance and management of a Cisco collaboration network, every task can be performed either from the Cisco Unified Communications Manager (CM) or natively on the endpoint. For example, in a Cisco Unified CM-centric environment, the TFTP server pushing a current firmware load to the endpoint can upgrade most endpoints registered. The exception to this rule is TC software-based endpoints, which would have to be upgraded manually on the endpoint itself. Other tasks, such as configuration backup and restore, can be performed natively on the endpoint. Multipoint conferences can be scheduled natively on a Cisco TelePresence MCU or a Cisco TelePresence Server, or ad hoc conferences can be created on the fly. So it would seem that so long as an organization has some sort of call control server, a multipoint control unit (MCU) and some endpoints that nothing else is needed for daily operation and support of the collaboration solution. This assumption is in fact true. However, as an organization grows and the collaboration solution expands, these remedial tasks can become quite cumbersome. Therefore, there is a tool that can be used to simplify how a Cisco collaboration solution is managed. This tool is known as the Cisco TelePresence Management Suite (TMS). TMS brings minimal functionality to the table that cannot already be performed on another device. The advantage of using TMS is its capability to streamline and simplify the daily tasks of using and managing a Cisco collaboration network all from a single, easy-to-use web interface. This chapter is not intended to give an exhaustive explanation of all the tasks TMS is able to perform. Instead, this chapter introduces a few of the most common tasks for which TMS is used. Those tasks include how to add systems to TMS, how to view open tickets on those systems, how to schedule and manage conferences from TMS, and an overview some of the reporting tools available on TMS.

Chapter 16: Cisco TelePresence Management Suite

TMS can provision the Cisco TelePresence MCU and Cisco TelePresence Server as well. Either of these products can be leveraged when conferences are scheduled on TMS, along with the multisite feature on endpoints, the Cisco Conductor, and third-party MCUs. TMS will decide which product to used based on the number of endpoints added to a conference, the types of endpoints added, and the number of ports available on different MCU products. There is an advanced Conference configuration setting on TMS that influences how TMS makes this decision, called External MCU Usage in Routing. To verify or change this setting, navigate to Administrative Tools > Configuration > Conference Settings and scroll down to the Advanced section at the bottom of the page. The External MCU Usage in Routing parameter contains the following options: Always will schedule an MCU in every scheduled call, even if only two endpoints are scheduled to communicate. Therefore, there is another setting called Always Except Point to Point . This setting will always include an MCU in scheduled conferences except for point-to-point scheduled calls. The Multisite option will never be used when Always or Always Except Point to Point are configured. If an administrator wants to use multisite whenever possible to preserve MCU resources, then there is a third setting that must be selected under this menu option. Only If Needed uses the multisite option on one of the scheduled endpoints whenever conferences are scheduled with few enough endpoints that multisite can support all the participants. If multisite cannot be used to support the conference for any reason, TMS will select an MCU to host the call. Figure 16-2 show these External MCU Usage in Routing settings and other options on the Cisco TMS.

Before conferences can be scheduled on TMS, endpoints and MCUs must be added to TMS so that it can manage them. Before you begin adding systems to TMS, it is recommended to first create folders. The structure of this tree hierarchy will greatly impact every other function performed on TMS. Folders and systems are added to TMS under the System > Navigator menu. In the Folder View section, select the folder within which you will create your various subfolders. Click the New Folder button. When the New Folder window displays, enter a name for the folder you are creating and click the Save button. This process can be repeated to create all the folders and subfolders needed to represent your corporation. Figure 16-3 shows how to add folders in TMS.

Figure 16-3 Adding Folders in TMS

After all the folders have been created, select a folder that you want to add devices to and click the Add Systems button. There are various ways devices can be added to TMS. For simplicity, this section only discusses how to add systems to TMS using the Add by Address tab. In the box under the Specify Systems by IP Address or DNS Names section, enter the IP address or URI of the systems you want to add. Multiple addresses can be added here using either a comma between them or a hyphen to represent a range of IP addresses. Expand the Advanced Settings section and enter the username and password of the systems you are adding to TMS. Click the Next button at the bottom of the page to start the system discovery process on TMS. Figure 16-4 shows how to add systems to TMS for TMS to manage them.

Cisco TelePresence MCU will be reserved for conference. Owner is the default owner of the conference. This is determined by the administrator account used to log in to TMS. The owner of a conference can be changed, allowing conference creators to generate scheduled conferences on behalf of someone else. Start Time allows administrators to set the start date and time of conference. By default, the start date and time will always be the date and time the Booking menu was opened. Conferences can be scheduled to start immediately or for any time in the future. Similarly, End Time allows administrators to set the end date and time for scheduled conferences. The end time will always default to 30 minutes after the start time because the default conference duration is set to 30 minutes. The end time can be changed to any variation of time from the start time. Duration allows administrators to set the length of time allotted to the scheduled conference. As it has already been mentioned, the default duration is 30 minutes. Clicking on the Recurrence button will open a new window. If you want the conference being scheduled to occur at different points in the future, recurrence settings can be configured. Recurrence Pattern allow the choice of Daily, Weekly, or Monthly. Range of Recurrence offers choices of when the recurrences should cease. The Advanced Settings parameters on the New Conference page include several options: ■

The Picture Mode drop-down menu allows administrators to choose from one of the three “view modes” discussed in Chapter 13, “Cisco Multipoint Solution.” The view modes are Continuous Presence, Voice Switched, and Enhanced CP.

■

IP Bandwidth is not a bandwidth limitation, though it effectively operates as though it is

a limit. Because TMS controls either the MCU calling out to the endpoints, or the endpoint dialing into the MCU, this setting determines the bandwidth rate that will be used. The range is from 64 kbps to 6144 kbps. If a participant were to dial in to the MCU ■

manually, any bandwidth rate could be used. ISDN Bandwidth is not a limitation either. Once upon a time, most endpoints could support both ISDN and IP communication protocols natively. Therefore, TMS could be used to schedule ISDN calls using IP to communicate with the endpoint. This setting allows administrators to set the number of B channels followed by the bandwidth in kbps.

■

The Secure drop-down menu allows for encryption to be enforced if necessary for all participating devices scheduled in this conference. The options are No, Yes, and If Possible.

■

Billing Code is a feature that controlled a billing code setting native on MXP endpoints.

Though these endpoints are end of sale, this feature still exists in TMS. ■

PIN will protect conferences from unwanted participants for joining. Any participants

who attempt to dial in to a conference that is PIN protected will be prompted to enter the PIN before they are allowed to join. If the MCU dials out to a participant, the PIN protection will not prevent the call from connecting.

16

CCNA Collaboration CIVND 210-065 Official Cert Guide ■

Extend Mode is a setting that allows conference times to be extended if the confer-

ence has run its length and participants still need more time to communicate. This dropdown menu offers three settings. Off prevents meetings from automatically extending. Endpoint Prompt displays an “Extend Meeting” message on compatible endpoints both 5 minutes and 1 minute before the end time of the conference. Automatic Best Effort enables the automatic extension of scheduled conferences by 15 minutes up to a maximum of 16 times in a single conference. Click the Add Participants button to add participants to the conference. A pop-up window will open, so be sure to either turn off pop-up blocker or add an exception for this pop-up window to allow it to open. From the Add Participants window, you can add the conference participants using the different tabs. Figure 16-6 shows the different tabs available from the Add Participants window.

Figure 16-6 Add Participant Window for Conference Creation on TMS

The Last Used tab allows administrators to add participants from previous bookings. The Endpoints and Rooms tab allows endpoints and rooms that are managed by Cisco TMS to be added to conferences. The Users tab allows adding users who possess accounts within TMS. If a user has an endpoint associated with his or her account, that endpoint will be added to the conference. The users added through this method will automatically receive an e-mail confirmation that they have been scheduled for a conference at their e-mail account listed in their user account. MCUs allows administrators to add MCUs that are managed by TMS. It is not necessary to add an MCU to a scheduled conference because TMS will select the best option for you based on the External MCU Usage in Routing setting discussed in the previous section. However, if an administration wants to select a specific MCU, this

Java requires administrators to log in again. Use the same credentials you would use to log in to TMS. The Conference Control Center gives you total control over the active conference. On the Search frame, you can locate the conference that you would like to control. After you have selected the conference, voluminous conference-related information will be displayed. From the Participants tab, you can view a list of participants, including a preview of information about them, and control the picture mode. Use the Participant Status, Event Log, and Graphical View tabs for additional control of the conference. Selecting a participant will display a list of conference management tools that can be used for various purposes. Some of the controls include dial a participant, disconnect a participant, mute the audio and video, allow a participant to occupy the main screen of the conference, and send a text message. Most of the conference control functions available natively on the MCU can be performed from the Conference Control Center on TMS. Figure 16-8 shows how the Conference Control Center would appear to an administrator.

Figure 16-8 Cisco TMS Conference Control Center Note TMS is very particular about what version of Java is supported per the version

of TMS running within a customer network. When accessing the Conference Control Center on TMS, if Java indicates an error, or denies access to the Conference Control Center, consult the Cisco TMS Administration Guide for the appropriate version of Java that should be used with TMS.

TMS Reporting The Cisco TMS reporting tool is a powerful and robust tool. TMS sources data from all the devices it manages to populate the reports that are generated automatically. To view system reports in Cisco TMS, move your mouse over the Reporting tab. A drop-down menu of all the reports available in TMS will be listed. Figure 16-9 illustrates the conference statistics displayed from the TMS Reporting menu.

CHAPTER 17

Cisco WebEx Solutions With the ever-changing workplace, keeping up with business needs and trends can often be a strenuous task. Add in the complexity and frequency with which newer technologies are entering the market, and it becomes increasingly obvious why businesses that cannot keep up with these trends fail. In an effort to stay in front of these workplace transformations, Cisco seeks out key acquisitions that keep them at the top of the market as number one or two in any commerce of which they are a part. One key acquisition Cisco made in 2007 was a company known as WebEx. With keen foresight about the direction the industry was heading, WebEx has placed Cisco strongly in the number-one position for cloud-based collaboration meeting space solutions. Cisco has continued to develop the service offering available with WebEx, recently launching the Collaboration Meeting Rooms (CMR) solution. This chapter introduces the different WebEx solutions available in the market today and reviews some of the features and tools that enhance the collaboration experience.

WebEx Meeting Center can also be offered as an on-premises solution. The on-premises solution can be customized with the organization’s logo, and features are more easily managed. Cisco CMR Cloud and Cisco CMR Hybrid leverage WebEx Meeting Center Cloud to connect WebEx users and traditional TelePresence endpoints together in a single collaboration environment, while preserving the end-user experience. Cisco WebEx Connect IM brings together presence, enterprise IM, audio, video, web conferencing, and IP telephony through one client. Cisco WebEx Connect IM is similar to Microsoft Lync or Cisco Jabber. A client can be downloaded to a computer and communicates withjust the aWebEx cloud. There issubscription. no upfront investment, no maintenance or upgrade costs, predictable monthly So, it is easyand to implement and easy to scale as business needs change. Cisco WebEx Training Center offers all the same features as WebEx Meeting Center, with a few more options needed in a virtual classroom environment. Cisco WebEx Training Center delivers highly interactive classes and training online, with video, breakout sessions, and hands-on learning labs. This application of WebEx can be used to train employees or offer online courses. Scheduling tools allow administrators to schedule a series of sessions, offer open attendance, or require registration. Emoticons allow participants to interact with the presenter and each other. A coffee cup can be displayed to show you are on a break, a hand can be raised if you have questions, and other icons can be used at the presenter’s discretion to demonstrate participation. An attentiveness tool is built in that shows whether participants are on the WebEx page or if they are viewing something else on their computer. These are just a few of the options available with the Cisco WebEx Training Center solution. Cisco WebEx Event Center provides the tools that you need to deliver cost-effective and successful online events. These events could range from event planning and promotion, to delivery and post-event follow-up and campaign reporting. Cisco WebEx Event Center enables companies to host events with up to 3000 participants and to control every aspect of the event from who is invited to following up with participants after the event. Cisco WebEx Event Center can be used to qualify, track, and cultivate leads for your sales initiatives, and can capture attendee information that can be stored and accessed later. Cisco WebEx Support Center provides real-time IT support and customer service to employees and customers anywhere in the world. The Cisco WebEx Collaboration Cloud, which is a real-time global network that provides fast, reliable, and secure application delivery, provides all Cisco WebEx cloud services.

WebEx Meeting Center Because all WebEx products are based on the Cisco WebEx Meeting Center platform, this product warrants a more detailed description of the features offered. This chapter has already established that Cisco WebEx Meeting Center allows participants to present information, share applications, and collaborate on projects. It streamlines the meeting process with a centralized space for managing activities and information. Cisco WebEx Meeting Center can be used for collaborative sessions, internal and external meetings, product and project coordination demos, and sales presentations. Table 17-3 outlines the Cisco WebEx Meeting Center features that are discussed in this section.

WebEx uses the H.264 codec for multipoint high-quality video at 720p30. H.264 uses special compression algorithms that allow participants to stream HD video at low bandwidth rates of less than 1 Mbps. The Cisco WebEx full-screen video experience includes active speaker switching. The Cisco WebEx user interface has been modified to have a highquality video experience in all screen views. It is easy to use and automatically adjusts video quality for each participant according to the par ticipant’s network bandwidth because different users ca n send and receive different resolu tions. With the high- quality v ideo capabilities and the TCP st reaming c apabilities, Cisco WebEx Me eting Center is a secure application that can operate with high-qua lity video for any company from any location in the world. With Cisco WebEx Meeting Center, there are different ways to share content between participants, and content can be shared from any participant within the WebEx Meeting. The host of the meeting will have the Cisco WebEx ball icon displayed beside his or her name. Using the mouse to scroll over another participant’s name will reveal a Cisco WebEx ball that is grayed out. To “pass the ball” to another participant, simply click the grayedout ball beside that participant’s name. That participant then takes control of the meeting and now has the ability to share content. You can also click the grayed-out ball beside your own name to “take the ball.” If another participant is sharing content while the ball is passed, the content that is being shared will immediately drop from the session. Whoever is sharing content can choose to share a document, application, or their entire desktop. If a participant is sharing his desktop, another participant can request remote desktop control. A pop-up will display on the screen of the presenter, who must grant permission before another participant can take control. Resuming control of your own desktop is as simple as moving your mouse. After you have resumed control, the whole process must be repeated to grant someone else control again. Figure 17-1 illustrates content that is being shared over a WebEx Meeting Center session.

378

CCNA Collaboration CIVND 210-065 Official Cert Guide

Figure 17-1 Content Sharing over WebEx Meeting Center

Sharing content through WebEx is a great way to express ideas and engage other participant in the conversation. Sometimes, however, premeditated content is not enough. Therefore, Cisco also offers an integrated Whiteboard feature and annotation tools with each WebEx session. With the Whiteboard feature, a presenter can add text blocks and draw shapes, lines, or even draw free style. Different colors can be used to make objects and lines more pronounced. All participants within a meeting, to make a selection within a Whiteboard drawing, can also use name arrows. These same annotation tools used with the Whiteboard feature can be used within content being shared, for similar purposes. Examples of how these annotation tools can be used include circling or underlining a word, phrase, or graphic to draw participants’ attention to the topic being discussed. If a map is being shared, the name arrow can be used to show a participant’s location or an area that a sales rep is targeting. On a graphic showing sales projection for the next quarter, the annotation tools could be used to draw lines of where projections should be or to highlight key elements that will impact these projections. However these tools are used, Cisco WebEx Meeting Center makes communication across distances a whole lot better by engaging participants and emphasizing key topics in a presentation. Figure 17-2 illustrates some of the options that you can use with the Whiteboard feature on Cisco WebEx Meeting Center.

Figure 17-2 Cisco WebEx Meeting Center Whiteboard Feature

You do not have to use Cisco WebEx Event Center to support a large number of participants. Cisco WebEx Meeting Center can scale from one to hundreds of attendees. The host can then control what privileges each participant has within the meeting. The host may only want the participants to see and hear the information being shared, without offering any kind of interaction. Such an application may be a CEO making a state of the company address to an entire body of employees. If a presentation is being made and questions about the content are anticipated but time is of the essence, a chat-only feature can be allowed for the majority of participants and a smaller team of panelists can be used to answer questions as they are asked, while the main host continues with the presentation. Another great feature offered with Cisco WebEx Meeting Center is the ability to record meetings. With WebEx Premises, recorded meetings are stored on your local server. With Cisco WebEx Meeting Center Cloud, recorded meetings are stored in the cloud. Participants can then be invited to review recorded meetings or optionally download them for reference later. WebEx does have a storage fee for recordings, but because they can be downloaded, hosts can download and delete recorded meetings and then host access to the recorded meetings from their own on-premises streaming server. Cisco TelePresence Content Server (CTS) or Cisco Show and Share (SnS) are two great applications for streaming content. The Cisco Media Experience Engine (MXE) can be used to change the format and add analytics to the WebEx recorded content. Figure 17-3 illustrates the recording option available with Cisco WebEx Meeting Center.

In addition to all these other features available within a Cisco WebEx Meeting Center session, files and applications can be transferred to all participants within a WebEx session for download. The host simply has to enable the option to transfer a file. A pop-up window will appear with two options: Share File and Download. The host needs to click the Share File button and select the files or applications he wants to share. These selections appear in the same pop-up window on all participants’ computers. Then, if they just click one of the items in the list and then click the Download button, the item will download from WebEx to their personal computer. Figure 17-4 illustrates the pop-up window that can be used in WebEx Meeting Center to transfer files and applications.

CMR Hybrid, formerly known as Cisco TelePresence WebEx OneTouch 2.0, extends Cisco TelePresence meetings to Cisco WebEx users. It blends the ease of use and broad reach of both Cisco TelePresence and Cisco WebEx solutions into one collaborative solution. It enables two-way video, audio, and content sharing between attendees using any type of TelePresence endpoints and WebEx conference participants, including mobile users. With Cisco TelePresence WebEx OneTouch, a meeting host can launch a joint Cisco TelePresence and WebEx meeting with the simplicity of One Button to Push (OBTP). To schedule a meeting, an organizer can use a Microsoft Outlook integration that the WebEx Productivity Tools enable. The host selects the participants, adds the preferred TelePresence endpoint and the WebEx information, and sends the invitation to all participants. CMR Hybrid displays the participant list in the Cisco WebEx meeting client and in the welcome screen for the Cisco TelePresence attendees. Cisco Unified Communications Manager or Cisco TelePresence Video Communication Server (Cisco VCS) for Cisco TelePresence endpoints enables CMR Hybrid. Cisco VCS Expressway is required for connectivity to WebEx meetings through a corporate firewall. Supported Cisco TelePresence multipoint conferencing systems include Cisco TelePresence Server and Cisco TelePresence MCU. Scheduling of the CMR Hybrid conferences requires Cisco TelePresence Management Suite (Cisco TMS).

The first 17 chapters of this book cover the technologies, protocols, commands, and features required to beexam prepared to passcertified the 210-065 CIVND (Implementing Cisco Video Network Devices) to become as a CCNA Collaboration professional. Although these chapters supply the detailed information, most people need more preparation than just reading alone. This chapter details a set of tools and a study plan to help you complete your preparation for the exam. This short chapter has two main sections. The first section explains how to install the exam engine and practice exams from the CD that accompanies this book. The second section lists some suggestions for a study plan, now that you have completed all the earlier chapters in this book. Note Appendixes C, D, and E exist as soft-copy appendixes on the CD included in the

back of this book.

CHAPTER 18

Final Preparation Tools for Final Preparation This section lists some information about exam preparation tools and how to access the tools.

Exam Engine and Questions on the CD The CD in the back of the book includes the Pearson Cert Practice Test engine. This software presents you with a set of multiple-choice questions, covering the topics you will be likely find on the real exam. The Pearson Cert Practice Test engine lets you study the exam content (using study mode) or take a simulated exam (in practice exam mode). The CD in the back of the book contains the exam engine. Once installed, you can then activate and download the current CIVND exam from Pearson’s website. Installation of the exam engine takes place in two steps: Step 1.

Install the exam engine from the CD.

Step 2.

Activate and download the CICD practice exam.

Install the Exam Engine The following are the steps you should perform to install the software: Step 1. Step 2.

Step 3.

The Cisco Learning Network Cisco provides a wide variety of CCNA Collaboration preparation tools at a Cisco website called the Cisco Learning Network. Resources found here include sample questions, forums on each Cisco exam, learning video games, and information about each exam. To reach the Cisco Learning Network, go to http://learningnetwork.cisco.com, or just search for “Cisco Learning Network.” To access some of the features/resources, you need to use the login you created at Cisco.com. If you do not have such a login, you can register for free. To register, simply go to Cisco.com, click Register at the top of the page, and supply some information.

Memory Tables Like most Certification Guides from Cisco Press, this book purposefully organizes information into tables and lists for easier study and review. Rereading these tables can be very useful before the exam. However, it is easy to skim over the tables without paying attention to every detail, especially when you remember having seen the table’s contents when reading the chapter. Instead of simply reading the tables in the various chapters, this book’s Appendixes C and D give you another review tool. Appendix C, “Memory Tables,” lists partially completed versions of many of the tables from the book. You can open Appendix C (a PDF on the CD that comes with this book) and print the appendix. For review, you can attempt to complete the tables. This exercise can help you focus during your review. It also exercises the memory connectors in your brain; plus it makes you think about the information without as much information, which forces a little more contemplation about the facts. Appendix D, “Memory Table Answer Key,” also a PDF located on the CD, contains the completed tables to check yourself. You can also just refer to the tables as printed in the book.

Chapter-Ending Review Tools Chapters 1 through 17 each have several features in the “Exam Preparation Tasks” section at the end of the chapter. You may have used some of or all these tools at the end of each chapter. It can also be useful to use these tools again as you make your final preparations for the exam.

Study Plan With plenty of resources at your disposal, you should approach studying for the CCNA Collaboration exam with a plan. Consider the following ideas as you move from reading this book to preparing for the exam.

18

388

CCNA Collaboration CIVND 210-065 Official Cert Guide

Recall the Facts As with most exams, many facts, concepts, and definitions must be recalled to do well on the test. If you do not work with security technologies and features on a daily basis, you might have trouble remembering everything that might appear on the CCNA Collaboration exam. You can refresh your memory and practice recalling information by reviewing the activities in the “Exam Preparation Tasks” section at the end of each chapter. These sections will help you study key topics, memorize the definitions of important security terms, and recall the basic command syntax of configuration and verification commands.

Practice Configurations The CCNA Collaboration exam includes an emphasis on practical knowledge. You need to be familiar with switch features and the order in which configuration steps should be implemented. This means that hands-on experience is going to take you over the edge to confidently and accurately build or verify configurations (and pass the exam). If at all possible, you should try to gain access to some endpoints, such as 8945 or 9971 IP Video Phones, Jabber Client and Jabber Video for TelePresence soft clients, CTS 500, DX series endpoint, and any of the TC software-based endpoints. For registering and placing calls, you need access to the Cisco Unified Communications Manager (CM), Cisco IM and Presence Service, and Cisco Video Communication Server (VCS). For multipoint calls, you need access to a Cisco TelePresence MCU and a Cisco TelePresence Management Suite (TMS). I know that is a tall order, but we cannot avoid the fact that hands-on experience means you need to get your hands on some gear. If you have access to a lab provided by your company, take advantage of it. You might also have some Cisco equipment in a personal lab at home. Otherwise, there are a number of sources for lab access, including online rack rentals from trusted Cisco Partners and the Cisco Partner E-Learning Connection (PEC), if you work for a Partner. Nothing beats handson experience. In addition, you can review the key topics in each chapter and follow the example configurations in this book. At the least, you will see the command syntax and the sequence in which configuration commands should be entered.

Using the Exam Engine The Pearson Cert Practice Test engine on the CD lets you access a database of questions created specifically for this book. The Pearson Cert Practice Test engine can be used either in study mode or practice exam mode, as follows: ■

Study mode: Study mode is most useful when you want to use the questions for learning

and practicing. In study mode, you can select options like randomizing the order of the questions and answers, automatically viewing answers to the questions as you go, testing on specific topics, and many other options.

Chapter 18: Final Preparation ■

389

Practice Exam mode:This mode presents questions in a timed environment, providing

you with a more exam realistic experience. It also restricts your ability to see your score as you progress through the exam and view answers to questions as you are taking the exam. These timed exams not only allow you to study for the actual 210-065 CIVND exam, they also help you simulate the time pressure that can occur on the actual exam. When doing your final preparation, you can use study mode, practice exam mode, or both. However, after you have seen each question a couple of times, you will likely start to remember the questions, and the usefulness of the exam database may go down. So, consider the following options when using the exam engine: ■ Use the question database for review. Use study mode to study the questions by chapter, just as with the other final review steps listed in this chapter. Consider upgrading to the Premium Edition of this book if you want to take additional simulated exams. ■

Save the question database, not using it for review during your review of each book part. Save it until the end so that you will not have seen the questions before. Then, use practice exam mode to simulate the exam.

To select the exam engine mode, click the My Products tab. Select the exam you want to use from the list of available exams, and then click the Use button. The engine should display a window from which you can choose Study Mode or Practice Exam Mode. When in study mode, you can further choose the book chapters, limiting the questions to those explained in the specified chapters of the book.

VHS VHS Video Home System is a widely adopted videocassette recording ( VCR ) technology

that was developed by Japan Victor Company (JVC) and put on the market in 1976. It uses magnetic tape 1/2 inch (1.27 cm) in width. Video Communications Server (VCS) ControlA Cisco video call control element that

provides flexible and extensible video calling/conferencing capabilities to endpoints within an enterprise. It peers with VCS Expressway to provide firewall-traversal capabilities for endpoints on the inside of the firewall needing to call endpoints outside of the enterprise network. Video Communications Server (VCS) ExpresswayA Cisco video call control element

that provides flexible and extensible video calling/conferencing capabilities to endpoints outside of an enterprise. It peers with the VCS Control to provide firewall-traversal capabilities for endpoints on the outside of the firewall needing to call endpoints on the inside of the enterprise network. Virtual TelePresence Server (VTS) A software-based videoconferencing bridge used with

CUCM to enable multiparty audio/videoconferencing, and content sharing. VLAN Virtual local-area network, decouples network traffic so that quality of service can be

implemented. VoIP Voice over IP is a methodology and group of technologies for the delivery of voice

communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. VSM The Cisco Video Surveillance Manager (VSM) is the management and control plane for

the Cisco video-surveillance solution components. VTC Video telecommunication. Web access This setting is specific to the DX series endpoints. Web Access must be enabled

for administrators to access the web interface of DX endpoints. The web interface allows access to important log information. WebEx Event Center A WebEx cloud based solution designed for large scale virtual events,

such as Town Hall, Webinar, or other presentations that need to allow thousands of attendees with seamless platform, device, and TelePresence compatibility. WebEx Meeting Center A WebEx cloud based solution for web, audio, and

videoconferencing. Meeting Center provides a shared workspace accessible from any Mac, PC, smartphone, tablet, or even TelePresence endpoint. WebEx Meetings Server An slightly scaled-down, on-premises version of the WebEx

Meeting Center experience. WebEx One-Click An ad hoc option that allows you to launch a WebEx meeting with a

single click of a button. WebEx Support Center A WebEx cloud-based platform designed to allow companies to

offer remote technical support and live, personalized assistance for their customers.

YPrPb WebEx Training Center A WebEx cloud based solution aimed at providing an interactive,

highly customizable training platform for large scale online courses, online training, or other learning events. WSVGA Wide-screen VGA offers resolutions of 1024x600 and 1024x576 to what would

normally be a composite VGA connection. XLR A grounded audio connector commonly used with commercial and professional

equipment. YPrPb Y is the luminance a digital video feed; Prisand Pb are the primary red and primary blue chrominance of a videoof feed. The primary green provided through an algorithm based

on how much blue and red are used.

Chapter 9 Table 9-3 Phone Configuration Settings on the Cisco Unified CM Phone Configuration Setting

Description

MAC address

Unique identifier used by the Cisco Unified CM to identify the device when communication is initiated through the TFTP service.

Device pool

Device pools define sets of common characteristics for devices. The device pool structure supports the separation of user and location information. The device pool contains only device- and location-related information.

Phone button template

When adding phones, you can assign one of these templates to the phones or create a new template. Creating and using templates provides a fast way to assign a common button configuration to a large number of phones.

Calling search space (CSS)

Partitions can be seen as a collection of route patterns. DNs, route patterns, and translation patterns can all belong to specific partitions. Calling search spaces are an ordered list of route partitions, and they determine which partitions calling devices must search when they attempt to complete a call.

Owner

In Cisco Unified CM Version 10.0 and later, an owner of a phone must be identified. Who the owner of a phone is can be specified under the owner user ID, or this setting

Owner user ID

Required for Registration (Yes or No)

can be changed to anonymous (public/shared space). This setting identifies who the owner is of this phone.

Phone load name This setting is used to identify a specific firmware version the TFTP server is to use when a device tries to register. Allow control of The Computer Telephony Integration (CTI) control service device from CTI on the Cisco Unified CM allows a phone to be controlled by the Jabber soft client, meaning that when Jabber sends or receives a c all request, the media and signaling is rerouted through the associated phone. Device security profile

To enable security features for a phone, you must configure a new security profile for the device type and protocol and apply it to the phone. Only the security features that the selected device and protocol support display in the Security Profile Settings window.

: Phone Configuration Setting

Required for Registration (Yes or No)

Description

SIP profile

SIP profiles change SIP incoming or outgoing messages so that interoperability between incompatible devices c an be ensured. SIP profiles can be configured with rules to add, remove, copy, or modify the SIP Session Description Protocol (SDP).

Secure Shell user

Cisco Technical Assistanceand Center (TAC) uses SecureTAC for Shell for troubleshooting debugging. Contact further assistance.

Secure Shell password

Cisco TAC uses secure shell for troubleshooting and debugging. Contact TAC for further assistance.

Web access

This setting is specific to the DX series endpoints. Web access must be enabled for administrators to access the web interface of DX endpoints. The web interface allows access to important log information.

SSH access

This setting is specific to the DX series endpoints. SSH access must be enabled for administrators to access the command-line interface (CLI) of DX endpoints. The CLI allows access to important log information and allows administrators to issue certain commands for testing, configuring, and troubleshooting DX endpoints. C

No

Phone button template

When adding phones, you can assign one of these Yes templates to the phones or create a new template. Creating and using templates provides a fast way to assign a common button configuration to a large number of phones.

Calling search space (CSS)

Partitions can be seen as a collection of route patterns. No DNs, route patterns, and translation patterns can all belong to specific partitions. Calling search spaces are an ordered list of route partitions, and they determine which partitions calling devices must search when they attempt to complete a call.

Owner

In Cisco Unified CM Version 10.0 and later, an owner of Yes a phone must be identified. Who the owner of a phone is can be specified under the owner user ID, or this setting

Owner user ID

can be changed to anonymous (public/shared space). This setting identifies who the owner is of this phone.

No

Phone load name This setting is used to identify a specific firmware version No the TFTP server is to use when a device tries to register. Allow control of The Computer Telephony Integration (CTI) control serviceNo device from CTI on the Cisco Unified CM allows a phone to be controlled by the Jabber soft client, meaning that when Jabber sends or receives a c all request, the media and signaling is rerouted through the associated phone. Device security profile

To enable security features for a phone, you must Yes configure a new security profile for the device type and protocol and apply it to the phone. Only the security features that the selected device and protocol support display in the Security Profile Settings window.
